Hmm. On closer inspection that's not quite true. After the line x = x * PyLong_BASE + (dig & (PyLong_BASE - pmask)); x has a value of the form n * pmask, where pmask is a power of 2 and n is in the range [0, 2**DBL_MANT_DIG). It's still exactly represented, provided that FLT_RADIX is 2. (It's the multiplications by powers of 2 that get hairy when FLT_RADIX is 16, since they *can* lose information.) _______________________________________ 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
