suspect-devices/circuitpython/py/formatfloat.c, branch v1.5.2 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.5.2 2015-11-22T18:05:08+00:00 py/formatfloat: Handle calculation of integer digit for %f format properly. 2015-11-22T18:05:08+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-11-22T18:02:16+00:00 urn:sha1:3d6240ba1b4f6f33a27b9eed7e51286f95d4cbe9 %f prints true integer digit, so its calculation should happen before any exponential scaling. py/formatfloat: Workaround (fix?) incorrect rounding for %f format. 2015-11-22T16:09:28+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-11-22T16:09:28+00:00 urn:sha1:3c4c0698021a9eed5ab66b1c47c0180dd1fabcf4 py/formatfloat: Convert to fully portable implementation. 2015-11-22T15:54:05+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-11-22T13:42:09+00:00 urn:sha1:9aaccd4735d60798963212d72989a9b9d852fc6d This takes previous IEEE-754 single precision float implementation, and converts it to fully portable parametrizable implementation using C99 functions like signbit(), isnan(), isinf(). As long as those functions are available (they can be defined in adhoc manner of course), and compiler can perform standard arithmetic and comparison operations on a float type, this implementation will work with any underlying float type (including types whose mantissa is larger than available intergral integer type). stmhal: fix single precision float printing error 2015-09-11T20:09:50+00:00 Dave Hylands dhylands@gmail.com 2015-08-31T22:43:31+00:00 urn:sha1:9d6128acdccb463edfe9a3b7dbf86417643104bb Fixes #1435. py: Implement mp_format_float for doubles and use where appropriate 2015-05-17T20:47:11+00:00 stijn stinos@zoho.com 2015-05-16T08:54:19+00:00 urn:sha1:861670ba2ad6fe575de4a31c95c01070ed900391 This allows using (almost) the same code for printing floats everywhere, removes the dependency on sprintf and uses just snprintf and applies an msvc-specific fix for snprintf in a single place so nan/inf are now printed correctly. py/formatfloat.c: Fix format of floating point numbers near 1.0. 2015-04-12T12:06:20+00:00 Dave Hylands dhylands@gmail.com 2015-04-12T07:36:00+00:00 urn:sha1:b21786947fabbdef76824d899263bec51779738b In particular, numbers which are less than 1.0 but which round up to 1.0. This also makes those numbers which round up to 1.0 to print with e+00 rather than e-00 for those formats which print exponents. Addresses issue #1178. py: Move to guarded includes, everywhere in py/ core. 2015-01-01T20:32:09+00:00 Damien George damien.p.george@gmail.com 2015-01-01T20:27:54+00:00 urn:sha1:51dfcb4bb7613ed164952712d9a5235a7b833cde Addresses issue #1022. formatfloat.c: Typo fix in comment. 2014-07-17T17:45:58+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-07-17T14:48:35+00:00 urn:sha1:e3737b858a5422be22b5c8d6141e83ab3ec358d4 Add license header to (almost) all files. 2014-05-03T22:27:38+00:00 Damien George damien.p.george@gmail.com 2014-05-03T22:27:38+00:00 urn:sha1:04b9147e150d2d6fa3750f312fe328b6a71c1b28 Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/. Enhance str.format support 2014-04-01T08:17:33+00:00 Dave Hylands dhylands@gmail.com 2014-03-31T04:06:50+00:00 urn:sha1:baf6f14deb567ab626c1b05213af346108f41700 This adds support for almost everything (the comma isn't currently supported). The "unspecified" type with floats also doesn't behave exactly like python. Tested under unix with float and double Spot tested on stmhal
