suspect-devices/circuitpython/lib/libm, branch v1.4.6 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.4.6 2015-02-22T14:47:11+00:00 lib/libm: Add implementations of erf, erfc, lgamma, tgamma. 2015-02-22T14:47:11+00:00 Damien George damien.p.george@gmail.com 2015-02-22T14:47:11+00:00 urn:sha1:9ab94c468cb0d2a22eadbce2f493e016c462109e lib/libm: Add frexp and modf functions; use in stmhal; add tests. 2015-01-22T13:48:29+00:00 Damien George damien.p.george@gmail.com 2015-01-22T13:48:29+00:00 urn:sha1:6d1f5070ce97d76452ba48c2baa27d8f818a1545 Addresses issue #1081. stmhal: Add fake implementation of __aeabi_f2lz(). 2014-12-29T22:52:41+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-12-29T22:52:41+00:00 urn:sha1:8a2cc1c7e4c08aa83dc05a3b472caf1e71972d22 To make mp_obj_new_int_from_float() somehow work. lib/libm: Add acosh, asinh, atanh, tan; get working with stmhal. 2014-12-18T14:44:02+00:00 Damien George damien.p.george@gmail.com 2014-12-18T14:44:02+00:00 urn:sha1:f04329e93b7bfa5462f232832d64aac3dc52d5db acoshf, asinhf, atanhf were added from musl. mathsincos.c was split up into its original, separate files (from newlibe-nano-2). tan was added. All of the important missing float functions are now implemented, and pyboard now passes tests/float/math_fun.py (finally!). py: Add builtin round function. 2014-10-31T11:28:50+00:00 Damien George damien.p.george@gmail.com 2014-10-31T11:28:50+00:00 urn:sha1:1559a978100762efd84666befd134d5975ae8d4b Addresses issue #934. py: Implement divmod, % and proper // for floating point. 2014-09-13T17:43:09+00:00 Damien George damien.p.george@gmail.com 2014-09-13T17:43:09+00:00 urn:sha1:8594ce228011e6264f59ade4ff8a7f2bfa90a649 Tested and working on unix and pyboard. py and libm: Add asinf,acosf; print higher precision for float. 2014-09-11T21:24:45+00:00 Damien George damien.p.george@gmail.com 2014-09-11T21:24:45+00:00 urn:sha1:20beff9ae3ae50b44022595bcb6d27d195a08963 Also use less stack space when printing single precision float. Addition of asinf and acosf addresses issue #851. lib, libm: Add back dummy definition of tanf. 2014-08-29T22:24:00+00:00 Damien George damien.p.george@gmail.com 2014-08-29T22:24:00+00:00 urn:sha1:4d3fc4632681576eed8235f8b90b49a032c80218 lib: Add lib and libm, moving current files from stmhal. 2014-08-29T21:42:26+00:00 Damien George damien.p.george@gmail.com 2014-08-29T21:42:26+00:00 urn:sha1:8707ea34218a0aae071d4fb8d25e23273c828ea1 Top-level lib directory is for standard C libraries that we want to provide our own versions of (for efficiency and stand-alone reasons). It currently has libm in it for math functions. Also add atanf and atan2f, which addresses issue #837.
