Hmmm... I don't think I can understand that. If the precision of "double" were that bad, it wouldn't be possible to store dates up to a precision of milliseconds in a TDateTime. I have a discrepancy of 40 seconds here.

On Win64 all math is done with double precision, on win32 all literal floating point values in your code will be interpreted as Extended. Cast everything to Double and the result will be the same on Win64 and Win32. -- Bart _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
