Define "right". > I checked on OS X (x86) where FPC longdouble is 10-byte, FPC clongdouble > is 16-byte and GCC long double is 16 byte too. Maybe a heritage of PPC that did have a 128-bit fp type. But x86/x86_64 to my knowledge doesn't have such type, and I just tested and Linux uses unixtype; begin writeln(sizeof(clongdouble)); end. writes "10". Afaik some work has gone in softfloat in the last years, and maybe there is an emulated 128-bit type now, but that is news for me.

Which is why I recommended to double check in the first place. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
