[fpc-devel] IsLibrary and GetModuleFileName
Hi Is the IsLibrary and GetModuleFileName implemented on platforms other than Windows? I found a 'fpcylix' unit, but GetModuleFileName just returns 0. Nothing is implement? What about the IsLibrary function? Is that also a fake implementation on platforms other than Windows? -- Graeme Geldenhuys General error, hit any user to continue. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
[fpc-devel] FormatFloat bug
Hi, Attached is a application that demonstrates a bug in FormatFloat. All tests pass when run under Delphi, but test four fails under Free Pascal.

If I remember correctly: Bookkeepers rounding as implemented by the Intel processors. No own routines are used. It's left up to the processor.
