The idea's attractive. The problem is finding an integer type that's guaranteed to have enough bits to store the mantissa for the float (probably plus one or two bits more for comfort); for IEEE 754 this means a 64-bit integer type, and there aren't any of those in C89. (One could use two 32-bit integer variables, but that's going to get messy.) _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3166> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
