I want to reinforce and refine a bit of what's been written.
comp.lang.python *is* unusually useful. Note, by the way, that, among the four replies you first found, ALL FOUR were accurate and pertinent. In a world where a discussion group is better-than- average when *one* out of four of its replies is trustworthy, clp rates high. Please be aware that "their ... hex representation" is ambiguous. At the very least, you need to be sensitive--as perhaps you already are--to the possibility that a float's (or double's) representation in memory is hardware-dependent (and, depending on what you mean, potentially dependent on the version of Python implementation). If you pursue this area, you'll want to be on the look-out for "IEEE 754", the standard which ... well, is most standard <URL: http://en.wikipedia.org/wiki/IEEE_floating-point_standard >. -- http://mail.python.org/mailman/listinfo/python-list
