Dave Hylands c4029e5079 Add string formatting support for longlong and mpz. 2014-04-07 11:38:45 -07:00
Damien George 8270e3853d py: More robust int conversion and overflow checking. 2014-04-03 11:00:54 +00:00
Paul Sokolovsky 57207b8818 objint_mpz: Quick&dirty implementation of bitwise operations.
Made solely to unbreak int-long.py test which in turn uncovered thinko
with implementation of inplace ops. On mpz level, bitwise ops implemented
only for same-sign numbers, and are not efficient (unconditional calling of
mpn_cmp() is apparently superfluous).

Damien George bb4a43f35c py: Fix some bugs in mpz; add mpz_from_ll and mpz_set_from_ll.
A couple of bugs in mpn_shl, and overflow bug in mpz_set_from_int.

Damien George 5260810d70 py: Wrap mpz float functions in MICROPY_ENABLE_FLOAT. 2014-03-08 15:04:54 +00:00
Damien George 06201ff3d6 py: Implement bit-shift and not operations for mpz.
Implement not, shl and shr in mpz library.  Add function to create mpzs
on the stack, used for memory efficiency when rhs is a small int.
Factor out code to parse base-prefix of number into a dedicated function.

Damien George 510477557d py: Take out bitfield entries from their own structure.
Don't need to wrap bitfields in their own struct.  Compiler does the
correct thing without it.

Damien George c5ac2ac590 py: Start to implement shl/shr for mpz. Fix return void. 2014-02-26 16:56:30 +00:00
Damien George aca141269e py: Fix mpn_sub, was increasing wrong source pointer.
Also change int -> machine_int_t where appropriate.

Damien George 438c88dd2f Add arbitrary precision integer support.
Some functionality is still missing (eg and, or, bit shift), and some
things are buggy (eg subtract).
