This function computes (x**y)%z in an efficient way. For large arguments
this operation is otherwise not computable by doing x**y and then %z.
It's currently not used, but is added in case it's useful one day.
py/mpz: Complete implementation of mpz_{and,or,xor} for negative args.2016-02-03T22:13:39+00:00Doug Curriegithub.9.eeeeeee@spamgourmet.com2016-01-31T03:35:58+00:00urn:sha1:2e2e15cec2f85ece763f3f80152d759aecfad47c
For these 3 bitwise operations there are now fast functions for
positive-only arguments, and general functions for arbitrary sign
arguments (the fast functions are the existing implementation).
By default the fast functions are not used (to save space) and instead
the general functions are used for all operations.
Enable MICROPY_OPT_MPZ_BITWISE to use the fast functions for positive
arguments.
py/mpz: Fix conversion of float to mpz so it works on big endian archs.2016-01-08T17:56:58+00:00Damien Georgedamien.p.george@gmail.com2016-01-08T17:56:58+00:00urn:sha1:2adf7ec3dd4da9188be60e9536b401ab99189558py/mpz: Normalize (remove leading zeros) xor operation result.2015-11-22T20:03:18+00:00Paul Sokolovskypfalcon@users.sourceforge.net2015-11-22T20:03:18+00:00urn:sha1:b3be4710aaa53429c78d03a86e9be909dca923c0py/mpz: Fix bignum anding of large negative with smaller positive int.2015-10-01T21:35:06+00:00Damien Georgedamien.p.george@gmail.com2015-10-01T21:35:06+00:00urn:sha1:2065373f67b126edfc3e0f2519aaad0956902c14py/mpz: Force rhs of mpz_shl_inpl/mpz_shr_inpl to be unsigned.2015-10-01T17:01:37+00:00Damien Georgedamien.p.george@gmail.com2015-10-01T17:01:37+00:00urn:sha1:2f4e8511cd602a6110b3636c316b5cac21181bf3
Python semantics are that rhs of shift must be non-negative, so there's
no need to handle negative values in the underlying mpz implementation.
py/mpz: Raise NotImplError instead of failing assertion.2015-10-01T16:57:36+00:00Damien Georgedamien.p.george@gmail.com2015-10-01T16:57:36+00:00urn:sha1:4c02e54298b0f955c5d60023310b724baa890d67py: Fix handling of negative numbers in struct.pack of q/Q.2015-04-25T22:51:14+00:00Damien Georgedamien.p.george@gmail.com2015-04-25T22:51:14+00:00urn:sha1:9472907ae1906ccff7ce5cab24f0fa9d146c4534py: Support conversion of bignum to bytes.2015-04-25T22:16:39+00:00Damien Georgedamien.p.george@gmail.com2015-04-25T22:16:39+00:00urn:sha1:271d18eb08ec488ee45f8e6cd852e8236074f082
This gets int.to_bytes working for bignum, and also struct.pack with 'q'
and 'Q' args on 32-bit machines.
Addresses issue #1155.
