I think it would be useful for programs to be able to detect whether a system uses IEEE-754 double-precision values for the 'float' type. There is lots of detailed information about the float type in sys.float_info, but no simple "is IEEE" flag. On some C implementations, this is exposed as __STDC_IEC_559__.
