3. Run the Hardware Troubleshooter 

1. Open the Settings app and go to the Update & Security section.
2. Select Troubleshoot from the menu on the left.
3. Select BSOD from the right pane and click Run the troubleshooter.
4. Follow the instructions on the screen to complete the troubleshooter.

Another thing we can try is running Windows 10’s built-in troubleshooting tool. This is designed to deal with various system issues, including BSODs.

So, it might be helpful in this case, as well.

4. Run the SFC scan

1. Right-click on the Start Menu button, and open Command Prompt (Admin).
2. Enter the following line and press Enter: sfc/scannow

2. Paste the following command and press Enter:
   • DISM /Online /Cleanup-Image /RestoreHealth
3. Wait until the scan is finished.
4. Restart your computer and try updating again.

And the third troubleshooter we’re going to try is DISM. DISM stands for Deployment Image Servicing and Management.

As its name says, it reloads the system image, which can lead to solving potential BSOD issues.  The first part was the standard procedure.

As an alternative, we will also show you the procedure that utilizes the installation media below.

Drivers can often cause these types of errors, and sometimes updating the drivers doesn’t help, so you’ll have to find and reinstall the problematic driver.

Few users reported that their audio drivers were causing the INVALID FLOATING POINT STATE error, but the problem was fixed after reinstalling those drivers.

7. Remove problematic applications

Third-party applications can often cause this error to appear, and in order to fix this problem, you need to find and remove the problematic applications.

Your antivirus or firewall can cause this problem, therefore we recommend that you temporarily remove your antivirus program. Uninstalling the antivirus might not fix the problem.

Resetting Windows 10 is fairly simple, and in order to complete it you might need a bootable USB flash drive.

We also have to mention that Windows 10 reset will remove all files from your C partition, so be sure to back up your important files.

If the error appears again, it means that it is caused by your hardware.

9. Check your hardware

Blue Screen of Death errors are often caused by hardware, and if you installed any new hardware recently we suggest that you remove it or replace it.

If new hardware is not the problem, we advise you to check your RAM and all other major hardware components.

invalid floating point operation при установке игры

Данная ошибка может возникать при выполнении узлов импорта из 1С или при тестировании настроенного подключения. Диагностируется при интеграции с платформой 1С версии 8.3.10, использующей серверную архитектуру.

В случае если сценарий импорта из 1С выполняется интерактивно в интерфейсе DStudio, решение для данной ошибки следующее:

Значение переменной «DisableFloatExceptions» при правильной правке сценария отразится в настройках Deductor (Рис. 2)

Важно: При изменении и последующем сохранении сценария в DStudio данные изменения могут быть утеряны.

В случае если сценарий используется в пакетном режиме, решение следующее:

Необходимо использовать управляющий сценарий, в котором при помощи узла «Команда ОС» запускать на выполнение DStudio.exe с параметрами запуска сценария импорта из 1С. При этом сам сценарий импорта из 1С править вышеописанным способом не надо, значение переменной DisableFloatExceptions можно передавать в параметрах запуска сценария. В узле «Команда ОС» строка запуска будет примерно такой:

INVALID FLOATING POINT STATE error in Windows 10 [Fixed]

Blue Screen of Death errors are one of the most serious errors that you can encounter on Windows 10. These errors cause many problems.

Therefore, today we’re going to show you how to fix INVALID FLOATING POINT STATE errors.

Steps to fix INVALID FLOATING POINT STATE BSoD error

How can I fix the INVALID FLOATING POINT STATE error?

1. Update Windows 10

Windows updates are important for your system stability and safety. Therefore, we strongly advise you to download the latest patches by using Windows Update.

New patches are released frequently. Many of them offer security improvements, new features and various bug fixes related to both hardware and software. Therefore, be sure that you download them.

2. Download the latest drivers

Windows 10 requires drivers in order to work with your hardware. If your drivers are outdated or not compatible with Windows 10, you’ll encounter a Blue Screen of Death error such as INVALID FLOATING POINT STATE.

To fix this any many other BSoD errors, it’s important that you update your drivers.

You can do that simply by visiting your hardware manufacturer’s website and downloading the latest drivers for your device. Bear in mind that you might have to update all drivers on your PC to fix this problem.

You can also use Device Manager to update your drivers, but we have to mention that Device Manager doesn’t always download the latest drivers.

So, it’s usually better to search and download the necessary drivers manually. This solution shows you how to download drivers by using Device Manager.

2.1 Update drivers automatically

Searching for drivers on your own can be time-consuming. So, we advise you to use a tool that will do this for you automatically.

Choose a professional driver solution so you won’t have to manually search for your drivers. This software will always keep your operating system updated with the newest drivers available. It does an excellent job when it comes to missing, outdated, and corrupted drivers.

Various errors are the result of a malfunctioning driver. When this is the case, you may need to update or reinstall completely this specific component. As the process is not straight-forward to complete, we recommend using an automated tool for the job. Here’s how to do it:

DriverFix

Keep your Windows safe from any type of errors caused by corrupted drivers, by installing and using DriverFix today!

Disclaimer: this program needs to be upgraded from the free version in order to perform some specific actions.

3. Run the Hardware Troubleshooter

Another thing we can try is running Windows 10’s built-in troubleshooting tool. This is designed to deal with various system issues, including BSODs.

So, it might be helpful in this case, as well.

4. Run the SFC scan

The next troubleshooter we’re going to try is the SFC scan. This is a command-line tool that goes through your system searching for potential issues.

Of course, if resolving these issues is possible, the SFC scan will do it automatically.

5. Run DISM

And the third troubleshooter we’re going to try is DISM. DISM stands for Deployment Image Servicing and Management.

As its name says, it reloads the system image, which can lead to solving potential BSOD issues. The first part was the standard procedure.

As an alternative, we will also show you the procedure that utilizes the installation media below.

6. Reinstall your audio drivers

After uninstalling the driver, Windows 10 will install the default driver instead. If the default driver works well and your PC is stable, you can continue using it, or you can update the driver with the newer version.

Drivers can often cause these types of errors, and sometimes updating the drivers doesn’t help, so you’ll have to find and reinstall the problematic driver.

Few users reported that their audio drivers were causing the INVALID FLOATING POINT STATE error, but the problem was fixed after reinstalling those drivers.

7. Remove problematic applications

Third-party applications can often cause this error to appear, and in order to fix this problem you need to find and remove the problematic applications.

Your antivirus or firewall can cause this problem, therefore we recommend that you temporarily remove your antivirus program. Uninstalling the antivirus might not fix the problem.

So, it’s recommended you download and use a dedicated removal tool to remove all files associated with your antivirus. Many antivirus companies offer these tools for download, so be sure to use them.

8. Reset Windows 10

After Windows 10 reset is completed, you’ll have a fresh installation of Windows 10 without any third-party applications.

If the INVALID_FLOATING_POINT_STATE error is caused by software, you can fix it easily by performing a Windows 10 reset.

Resetting Windows 10 is fairly simple, and in order to complete it you might need a bootable USB flash drive.

We also have to mention that Windows 10 reset will remove all files from your C partition, so be sure to back up your important files.

If the error appears again, it means that it is caused by your hardware.

9. Check your hardware

Blue Screen of Death errors are often caused by hardware, and if you installed any new hardware recently we suggest that you remove it or replace it.

If new hardware is not the problem, we advise you to check your RAM and all other major hardware components.

INVALID FLOATING POINT STATE BSoD error can be a big problem, but we hope that you managed to fix this error by using our solutions.

Здравствуйте! 

Часто начала появляться ошибка «invalid floating point operation», обычно закрывается нажатием кнопки «ОК». Ошибка появляется при заполнении/редактировании сметы.

Не могу понять причину появления ошибки и её связь с какими либо действиями. Иногда совсем не появляется. Иногда появляется один раз и закрывается  нажатием кнопки «ОК». А иногда появляется окно с ошибкой, при нажатии на кнопку «ОК» ошибка закрывается и тут же появляется это же окно с ошибкой, далее программу приходится закрывать из диспетчера задач.

А иногда, после нескольких появлений вышеуказанной ошибки, РИК самостоятельно закрывается без каких либо сообщений.

Подозреваю что, что-то не так с системой, так как на другом компе проблем не возникает.

Система Win10, ошибка начала появляться после последнего крупного обновления винды за май 2020.

Если кто знает решение данной проблемы, будьте добры, помогите пожалуйста… усталлл

I’m getting a (repeatable) floating point exception when i try to Trunc() a Real value.

e.g.:

Trunc(1470724508.0318);

In reality the actual code is more complex:

 ns: Real;
 v: Int64;

 ns := ((HighPerformanceTickCount*1.0)/g_HighResolutionTimerFrequency) * 1000000000;
 v := Trunc(ns);

But in the end it still boils down to:

Trunc(ARealValue);

Now, i cannot repeat it anywhere else — just at this one spot. Where it fails every time.

It’s not voodoo

Fortunately computers are not magic. The Intel CPU performs very specific observable actions. So i should be able to figure out why the floating point operation fails.

Going into the CPU window

v := Trunc(ns)

fld qword ptr [ebp-$10]

This loads the 8-byte floating point value at ebp-$10 into floating point register ST0.

The bytes at memory address [ebp-$10] are:

0018E9D0: 6702098C 41D5EA5E    (as DWords)
0018E9D0: 41D5EA5E6702098C     (as QWords)
0018E9D0:   1470724508.0318    (as Doubles)

The call succeeds, and the floating point register the contains the appropriate value:

Next is the actual call to the RTL Trunc function:

call @TRUNC

Next is the guts of Delphi RTL’s Trunc function:

@TRUNC:

sub esp,$0c
wait
fstcw word ptr [esp]       //Store Floating-Point Control Word on the stack
wait
fldcw word ptr [cwChop]    //Load Floating-Point Control Word
fistp qword ptr [esp+$04]  //Converts value in ST0 to signed integer
                           //stores the result in the destination operand
                             //and pops the stack (increments the stack pointer)
wait
fldcw word ptr [esp]       //Load Floating-Point Control Word
pop ecx
pop eax
pop edx
ret

Or i suppose i could have just pasted it from the rtl, rather than transcribing it from the CPU window:

const cwChop : Word = $1F32;

procedure       _TRUNC;
asm
        { ->    FST(0)   Extended argument       }
        { <-    EDX:EAX  Result                  }

        SUB     ESP,12
        FSTCW   [ESP]              //Store foating-control word in ESP
        FWAIT
        FLDCW   cwChop             //Load new control word $1F32
        FISTP   qword ptr [ESP+4]  //Convert ST0 to int, store in ESP+4, and pop the stack
        FWAIT
        FLDCW   [ESP]              //restore the FPCW
        POP     ECX
        POP     EAX
        POP     EDX
end;

The exception happens during the actual fistp operation.

fistp qword ptr [esp+$04]

At the moment of this call, the ST0 register will contains the same floating point value:

Note: The careful observer will note the value in the above screenshot doesn’t match the first screenshot. That’s because i took it on a different run. I’d rather not have to carefully redo all the constants in the question just to make them consistent — but trust me: it’s the same when i reach the fistp instruction as it was after the fld instruction.

Leading up to it:

• sub esp,$0c: I watch it push the the stack down by 12 bytes
• fstcw word ptr [esp]: i watch it push $027F into the the current stack pointer
• fldcw word ptr [cwChop]: i watch the floating point control flags change
• fistp qword ptr [esp+$04]: and it’s about to write the Int64 into the room it made on the stack

and then it crashes.

What can actually be going on here?

It happens with other values as well, it’s not like there’s something wrong with this particular floating point value. But i even tried to setup the test-case elsewhere.

Knowing that the 8-byte hex value of the float is: $41D5EA5E6702098C, i tried to contrive the setup:

var
    ns: Real;
    nsOverlay: Int64 absolute ns;
    v: Int64;
begin
   nsOverlay := $41d62866a2f270dc;
   v := Trunc(ns);
end;

Which gives:

nsOverlay := $41d62866a2f270dc;

mov [ebp-$08],$a2f270dc
mov [ebp-$04],$41d62866

v := Trunc(ns)

fld qword ptr [ebp-$08]
call @TRUNC

And at the point of the call to @trunc, the floating point register ST0 contains a value:

But the call does not fail. It only fails, every time in this one section of my code.

What could be possibly happening that is causing the CPU to throw an invalid floating point exception?

What is the value of cwChop before it loads the control word?

The value of cwChop looks to be correct before the load control word, $1F32. But after the load, the actual control word is wrong:

Bonus Chatter

The actual function that is failing is something to convert high-performance tick counts into nanoseconds:

function PerformanceTicksToNs(const HighPerformanceTickCount: Int64): Int64; 
//Convert high-performance ticks into nanoseconds
var
    ns: Real;
    v: Int64;
begin
    Result := 0;

    if HighPerformanceTickCount = 0 then
        Exit;

    if g_HighResolutionTimerFrequency = 0 then
        Exit;

    ns := ((HighPerformanceTickCount*1.0)/g_HighResolutionTimerFrequency) * 1000000000;

    v := Trunc(ns);
    Result := v;
end;

I created all the intermeidate temporary variables to try to track down where the failure is.

I even tried to use that as a template to try to reproduce it:

var
    i1, i2: Int64;
    ns: Real;
    v: Int64;
    vOver: Int64 absolute ns;
begin
    i1 := 5060170;
    i2 := 3429541;
    ns := ((i1*1.0)/i2) * 1000000000;
    //vOver := $41d62866a2f270dc;
    v := Trunc(ns);

But it works fine. There’s something about when it’s called during a DUnit unit test.

All the CPU is doing is turning on a reserved, unused, mask bit.

RaiseLastFloatingPointError()

If you’re going to develop programs for Windows, you really need to accept the fact that floating point exceptions should be masked by the CPU, meaning you have to watch for them yourself. Like Win32Check or RaiseLastWin32Error, we’d like a RaiseLastFPError. The best i can come up with is:

procedure RaiseLastFPError();
var
    statWord: Word;
const
    ERROR_InvalidOperation = $01;
//  ERROR_Denormalized = $02;
    ERROR_ZeroDivide = $04;
    ERROR_Overflow = $08;
//  ERROR_Underflow = $10;
//  ERROR_InexactResult = $20;
begin
    {
        Excellent reference of all the floating point instructions.
        (Intel's architecture manuals have no organization whatsoever)
        http://www.plantation-productions.com/Webster/www.artofasm.com/Linux/HTML/RealArithmetica2.html

        Bits 0:5 are exception flags (Mask = $2F)
            0: Invalid Operation
            1: Denormalized - CPU handles correctly without a problem. Do not throw
            2: Zero Divide
            3: Overflow
            4: Underflow - CPU handles as you'd expect. Do not throw.
            5: Precision - Extraordinarily common. CPU does what you'd want. Do not throw
    }
    asm
        fwait                   //Wait for pending operations
        FSTSW statWord    //Store floating point flags in AX.
                                //Waits for pending operations. (Use FNSTSW AX to not wait.)
        fclex                   //clear all exception bits the stack fault bit,
                                //and the busy flag in the FPU status register
    end;

    if (statWord and $0D) <> 0 then
    begin
        //if (statWord and ERROR_InexactResult) <> 0 then raise EInexactResult.Create(SInexactResult)
        //else if (statWord and ERROR_Underflow) <> 0 then raise EUnderflow.Create(SUnderflow)}
        if (statWord and ERROR_Overflow) <> 0 then raise EOverflow.Create(SOverflow)
        else if (statWord and ERROR_ZeroDivide) <> 0 then raise EZeroDivide.Create(SZeroDivide)
        //else if (statWord and ERROR_Denormalized) <> 0 then raise EUnderflow.Create(SUnderflow)
        else if (statWord and ERROR_InvalidOperation) <> 0 then raise EInvalidOp.Create(SInvalidOp);
    end;
end;

A reproducible case!

I found a case, when Delphi’s default floating point control word, that was the cause of an invalid floating point exception (although I never saw it before now because it was masked). Now that i’m seeing it, why is it happening! And it’s reproducible:

procedure TForm1.Button1Click(Sender: TObject);
var
    d: Real;
    dover: Int64 absolute d;
begin
    d := 1.35715152325557E020;
//  dOver := $441d6db44ff62b68; //1.35715152325557E020
    d := Round(d); //<--floating point exception
    Self.Caption := FloatToStr(d);
end;

You can see that the ST0 register contains a valid floating point value. The floating point control word is $1372. There floating point exception flag are all clear:

And then, as soon as it executes, it’s an invalid operation:

• IE (Invalid operation) flag is set
• ES (Exception) flag is set

I was tempted to ask this as another question, but it would be the exact same question — except this time calling Round().

т.е мне ненужно выводить сообщение о том что число под корнем отрицательное, оно должно считаться и сравниваться с Эпсилонтом в DfX2 значение все равно отрицательное и как его посчитать не знаю.
А решаю задачу многомерной оптимизации состоящую из 7 шагов
1- ввожу X1,X2;
2- нахожу их значения в функции F(X1,X2) у меня

1
2

Fvek:=Func(X1);
Fvek2:=Func1(X2);

A1:=Fvek+Fvek2; получаю значение функции
3-нахожу производную для X1,X2

1
2

DfX1:=Df1(X1);
DfX2:=Df2(X2);

4-нахожу новый X1,X2 подставл производную в формулу
X1:=X1-L*DfX1;
X2:=X2-L*DfX2;
5-нахожу их значения в функции F(X1,X2) уже с новыми X1,X2

1
2
3

Fvek:=Func(X1);
 Fvek2:=Func1(X2);
 A2:= Fvek+Fvek2;

6-проверяю A1 и A2 если A1 >A2 тогда идем дальше если нет то цикл должен выполниться еще раз и уменьшить шаг т.е L:=L/2 это я в коде еще не реализовал
7—нахожу новые производные для X1,X2

1
2

DfX1:=Df1(X1);
DfX2:=Df2(X2);

и пытаюсь впихнуть их в корень

1
2
3

b1:=Sqrt(DfX1);
 b2:=Sqrt(DfX2);
 sum:=b1+b2;

проверяю условием
sum > Eps то выполняем еще иначе получаем долгожданный ответ.

У тебя, в твоем разбросанном коде гдето или выполняется конвертация строки в число или присвоение значения, и при этом не выполняется проверка на региональные установки. Т.е. вместо точки стоит запятая, или наоборот. Например, если региональные установки русские, этот код скорее всего сгенерит исключение:

Код:

З.Ы. Только без обид — для вопросов на подобные темы есть форум «Сообщества чайников», если актуально — начать стоит с него.
