Hi,
does we have in FPC something like Delphi {$FINITEFLOAT OFF} ?
If not can be implemented in future ?I am trying to avoid FPU exception in case of underflow or overflow values. I have this test code: d := 30000; // + or -d := 1/(1+exp(-1*d)); // here I get SIGFPE exception (my guess is that it is caused by value underflow -INF or overflow +INF
What can I do in this case ? I did: SetExceptionMask(GetExceptionMask() + [exUnderflow,exOverflow]); It seems to work, but it depends on Math unit, which I want to avoid. Then I did: CW := Get8087CW; SSECW:=GetSSECSR; Set8087CW(CW or $18); // mask underflow,overflow SetSSECSR((SSECW and $ffffe07f) or (dword($58) shl 7)); It works for Win32, but not for Win64 ? TIA -Laco. _______________________________________________ fpc-pascal maillist - [email protected] http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
