| | | | | | The patch is collaborated work of Mark Dickinson and me. It was mostly done a few months ago. The patch fixes a lot of loose ends and edge cases related to operations with NaN, INF, very small values and complex math. The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :)

For example repr(11./5) now returns '2.2' instead of '2.2000000000000002'. Thanks to noam for the patch! I had to modify doubledigits.c slightly to support X64 and IA64 machines on Windows.

[ 1181301 ] make float packing copy bytes when they can which hasn't been reviewed, despite numerous threats to check it in anyway if noone reviews it. Please read the diff on the checkin list, at least! The basic idea is to examine the bytes of some 'probe values' to see if the current platform is a IEEE 754-ish platform, and if so _PyFloat_{Pack,Unpack}{4,8} just copy bytes around. The rest is hair for testing, and tests.
