Dag-Erling Smørgrav	c5b962387c	Add mpi_eq_abs() and mpi_eq() predicates.	2014-12-30 11:12:11 +00:00
Dag-Erling Smørgrav	bc8e9d67ba	In both mpi_add_abs() and mpi_sub_abs(), make sure that the target is ... untouched if the operation fails. Also ensure that A = A +/- A works.	2014-12-29 23:44:34 +00:00
Dag-Erling Smørgrav	98c6349d4a	In mpi_zero(), save a memset() if the target is already zero.	2014-12-29 23:22:54 +00:00
Dag-Erling Smørgrav	1412dac680	Shifting any number by zero places is a no-op, but so is shifting zero by ... any number of places.	2014-12-29 23:20:26 +00:00
Dag-Erling Smørgrav	8228f19d5a	In mpi_copy(), any failure should leave the target untouched.	2014-12-29 23:18:57 +00:00
Dag-Erling Smørgrav	82f5c5cf77	In mpi_load(), use be32dec() when possible. ... In mpi_set(), it is impossible for the value being loaded to exceed the minimum size of an mpi; thus, there is no need for mpi_grow().	2014-12-29 15:08:09 +00:00
Dag-Erling Smørgrav	d4fd9a1958	rm unused variable	2014-08-12 07:33:30 +00:00
Dag-Erling Smørgrav	be31515f5e	Start of a multiple-precision integer arithmetic library.	2014-08-12 07:30:31 +00:00
