Stefan Krah <ste...@bytereef.org> added the comment:
MAX_PREC is chosen so that 5*MAX_PREC does not overflow 32-bit or 64-bit signed integers. This eliminates many overflow checks for the exponent. Updating the exponent is (perhaps surprisingly) quite performance sensitive, that's why the 32-bit build does not use a 64-bit exponent. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39576> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
