suspect-devices/circuitpython/py/objint.c, branch v1.9.1 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.9.1 2017-05-06T00:29:09+00:00 py/objint: In int.from_bytes, only create big-int if really needed. 2017-05-06T00:29:09+00:00 Damien George damien.p.george@gmail.com 2017-05-05T11:42:39+00:00 urn:sha1:58bb73e010301235b32c3b81575af21cca55f2a7 This patch ensures that int.from_bytes only creates a big-int if necessary, by checking the value for a small-int overflow as it's being parsed. py/objint: Use unsigned arithmetic when formatting an integer. 2017-04-11T05:18:35+00:00 Damien George damien.p.george@gmail.com 2017-04-11T05:18:35+00:00 urn:sha1:e31fbd9b41315963aaca732e7585fc4cb10ccbcd Otherwise the edge case of the most negative integer value will not convert correctly. py/objint: Extract small int value directly because type is known. 2017-04-11T05:16:09+00:00 Damien George damien.p.george@gmail.com 2017-04-11T05:16:09+00:00 urn:sha1:f66df1efc85fe9fc7fd0b2125792d02001de48bb py/objint: Consolidate mp_obj_new_int_from_float to one implementation. 2017-04-04T06:45:49+00:00 Damien George damien.p.george@gmail.com 2017-04-04T06:45:49+00:00 urn:sha1:fc245d1ca4367f9876ac32c7e08e169da7db79b9 This reduces code duplication and allows to make mp_classify_fp_as_int static, which reduces code size. py: Change mp_uint_t to size_t for mp_obj_str_get_data len arg. 2017-03-29T01:56:45+00:00 Damien George damien.p.george@gmail.com 2017-03-25T08:48:18+00:00 urn:sha1:6b341075376705ee1fe9e003b76b09afa59778f4 py/objint: Handle special case of -0 when classifying fp as int. 2017-03-23T12:51:35+00:00 Damien George damien.p.george@gmail.com 2017-03-23T12:51:35+00:00 urn:sha1:c073519ec824145676edef88623496c1ded4fae5 Otherwise -0.0 is classified as a bigint, which for builds without bigints will lead unexpectedly to an overflow. py/objint: Allow to print long-long ints without using the heap. 2017-03-14T03:54:20+00:00 Damien George damien.p.george@gmail.com 2017-03-14T03:54:20+00:00 urn:sha1:d1ae6ae080e1475b50aa2c6580d1ea588cfbdf64 Some stack is allocated to format ints, and when the int implementation uses long-long there should be additional stack allocated compared with the other cases. This patch uses the existing "fmt_int_t" type to determine the amount of stack to allocate. py/objint: Convert mp_uint_t to size_t where appropriate. 2017-02-16T05:51:17+00:00 Damien George damien.p.george@gmail.com 2017-02-16T05:41:43+00:00 urn:sha1:da36f5232dcf02c448ee9933e358b711cfe03f30 py/objint: Fix left-shift overflow in checking for large int. 2017-01-25T03:39:13+00:00 Damien George damien.p.george@gmail.com 2017-01-25T03:39:13+00:00 urn:sha1:eaa77455c37cf18670d181556e6d17e0b01c2267 py/objint: from_bytes(): Implement "byteorder" param and arbitrary precision. 2017-01-21T17:14:18+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-01-21T17:14:18+00:00 urn:sha1:bec7bfb29d76f995dbf223c20f5d04ae1e33cee6 If result guaranteedly fits in a small int, it is handled in objint.c. Otherwise, it is delegated to mp_obj_int_from_bytes_impl(), which should be implemented by individual objint_*.c, similar to mp_obj_int_to_bytes_impl().
