When I host the application on one server, I have no problems. The viewstate is invalid for this page and might be corrupted. Viewstate invalid when I load the application in load balanced server I'm not sure with the info given above whether should I ask, but would you give me some hint about in which case this kind of problem will occur? I'm not sure from which part the problem is, but without fastmm the problem will go away. The problem is in some circumstance my program will raise a EInvalidOP "Invalid floating point operation" error when the program is accessing the a "Single" property of a object in a TObjectList. Understand this format, some or all of this message may not be legible.Ĭontent-Type: text/plain charset="Utf-8"Į.delphi.generalĬontent-Type: application/x-zip-compressed įastMM and the strange EInvalidOP "Invalid floating point operation" error.īefore I start I have to first claim I might not be provide the very specific context for my question. Invalid floating point operation error with "power". Do I need to useĪn end run and simply convert the number to a logarithm then multiply it by the exponent, andįinally, take the anti log of the result?
I would appreciate any assistance or suggestions that anyone might have. the function works ok with an exponent of any Use the power function to raise a number, which is less than one, but not negative, to a power thatĬontains a decimal part, e.g., power(.925, 4.25).
#FLOATING POINT ERROR WITH REMOTE UTILITIES CODE#
My code is raising an error message "invalid floating point operation" when i attempt to Invalid floating point operation error with "power" TPoint pstlScPt = PlotSurface->ClientToScreen(TPoint(PlotSurface->PlotRect.Left, PlotSurface->PlotRect.Top)) īounds.right = bounds.left + PlotSurface->PlotRect.Width() Create a bounding rect in screen coords to move this control within. Void _fastcall T2DPlotCursor::ManualMoveCursorPosition(double xRatio, double yRatio) I have no idea why! I have also listed the debuggers values for the variables. On the last line of code below an EInvalidOp exception is thrown. At that point this pro.ĮInvalidOp Invalid Floating Point Operation The problem is when C gets assigned to Result. Now, GetValue(C) ALWAYS succeeds, there's ALWAYS a valid Currency number read. There's a Currency field in the dataset and the code above at some point executes this from DB.pas:ħ315 function TBCDField.GetAsVariant: Variant ħ319 if GetValue(C) then Result := C else Result := Null I'm reading field values from a dataset, something like this: Invalid floating point operation in Variants._VarFromCurr I have a debug information in assembler, I have checked the source code of Move and the problem happens in FILD instruction, I found that FILD converts an integer value from memory to float point in a register and it could trigger that invalid operation, but why that happens? I´m stuck with this for 2 days now It's like building airport in the place of telephone booth.I´m experiencing an weird issue that I have never seen before, sometimes when using the routine CopyMemory (Which internally calls Move) I get an Invalid Float Point Operation exception, when such thing could happen when using Move? well, scripts (with loading from cli of autoit3.exe).Ģ) I have to work with some dynamically generated scripts, so right now to work it out i have to generate scripts, compile them with auto2exe.exe /in /out, and run this compiled files.

With some msgbox's help i found that this error (Floating point support) pop-ups on the next line:Īnd again, if i'll compile this file with auto2exe.exe (into shiftperiod.exe) it'll work fine without any errors.ġ) how to make both this scripts work as. $t=ControlGetText("Active","","")įirst 5 lines works perfectly ($t always gets right text from form, and its format: mm/yyyy) When i'm trying to run it as script (through autoit3.exe), im getting MS VC++ error 6002:īut if i will compile it with auto2exe.exe into value.exe, it gives me right message box (with value 0.66666667)Īlso, i'm having trouble with next part of the script:
