Damien George	65402ab1ec	py/mpz: Do Python style division/modulo within bignum divmod routine. This patch consolidates the Python logic for division/modulo to one place within the bignum code.	2016-05-08 22:21:21 +01:00
Damien George	dc3faea040	py/mpz: Fix bug with overflowing C-shift in division routine. When DIG_SIZE=32, a uint32_t is used to store limbs, and no normalisation is needed because the MSB is already set, then there will be left and right shifts (in C) by 32 of a 32-bit variable, leading to undefined behaviour. This patch fixes this bug.	2016-05-08 21:38:43 +01:00
Damien George	539681fffd	tests: Rename test scripts, changing - to _ for consistency. From now on, all new tests must use underscore. Addresses issue #727.	2014-07-05 06:14:29 +01:00
