suspect-devices/circuitpython/py/objint_longlong.c, branch v1.4.5CircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.4.52015-05-12T21:46:02+00:00py: Convert hash API to use MP_UNARY_OP_HASH instead of ad-hoc function.2015-05-12T21:46:02+00:00Damien Georgedamien.p.george@gmail.com2015-05-11T12:25:19+00:00urn:sha1:c2a4e4effc81d8ab21bb014e34355643e5ca0da2
Hashing is now done using mp_unary_op function with MP_UNARY_OP_HASH as
the operator argument. Hashing for int, str and bytes still go via
fast-path in mp_unary_op since they are the most common objects which
need to be hashed.
This lead to quite a bit of code cleanup, and should be more efficient
if anything. It saves 176 bytes code space on Thumb2, and 360 bytes on
x86.
The only loss is that the error message "unhashable type" is now the
more generic "unsupported type for __hash__".
py: Implement power op for long-long implementation of bignum.2015-04-25T22:28:10+00:00Damien Georgedamien.p.george@gmail.com2015-04-25T22:28:10+00:00urn:sha1:0f553fe10b14051aca25818b0aeac175c60889e0py: 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.

py: Partially fix float to int conversion.2014-12-29T22:22:50+00:00Paul Sokolovskypfalcon@users.sourceforge.net2014-12-29T22:22:10+00:00urn:sha1:12033df511a5a5f0237a764379aacfbceb6c45dd
This fixes conversion when float type has more mantissa bits than small int,
and float value has small exponent. This is for example the case of 32-bit
platform using doubles, and converting value of time.time(). Conversion of
floats with larg exponnet is still not handled correctly.
py: Rename mp_obj_int_get to mp_obj_int_get_truncated; fix struct.pack.2014-12-05T23:13:52+00:00Damien Georgedamien.p.george@gmail.com2014-12-05T23:13:52+00:00urn:sha1:be6d8be91e133e98117025062df0e63aaf87efd2
mp_obj_int_get_truncated is used as a "fast path" int accessor that
doesn't check for overflow and returns the int truncated to the machine
word size, ie mp_int_t.
Use mp_obj_int_get_truncated to fix struct.pack when packing maximum word
sized values.
Addresses issues #779 and #998.

py: Correctly set sys.maxsize value for 64-bit.2014-09-06T17:22:06+00:00Paul Sokolovskypfalcon@users.sourceforge.net2014-09-06T16:17:23+00:00urn:sha1:722e562736f83865333d8b3dd942f903b9db8a7c
Type representing signed size doesn't have to be int, so use special value
which defaults to SSIZE_MAX, but as it's not defined by C standard (but rather
by POSIX), allow ports to set it.
