suspect-devices/circuitpython/lib/libm/math.c, branch 2.x CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=2.x 2017-10-16T19:20:33+00:00 1. Use lib/libm for small (non-Express builds) to gain back a lot of flash space. 2017-10-16T19:20:33+00:00 Dan Halbert halbert@halwitz.org 2017-10-15T18:02:42+00:00 urn:sha1:dbd3f1516854f8609fe886d83b556b73684fdc6a 2. Add flag INTERNAL_LIBM to mpconfigboard.mk files to signal using lib/libm. 3. Fix floating-point warnings in lib/libm 4. Turn off -finline-limit, no longer needed due to 1. 5. Add explicit flags for SPI_FLASH_FILESYSTEM and INTERNAL_FLASH_FILESYSTEM to mpconfigboard.mk files, so they don't need to know the name of the .c file that implements those. Makefile takes care of checking the flags and including the right files. all: Use the name MicroPython consistently in comments 2017-07-31T08:35:40+00:00 Alexander Steffen devel.20.webmeister@spamgourmet.com 2017-06-30T07:22:17+00:00 urn:sha1:55f33240f3d7051d4213629e92437a36f1fac50e There were several different spellings of MicroPython present in comments, when there should be only one. lib/libm/math: Remove implementations of float conversion functions. 2017-06-14T07:18:23+00:00 Damien George damien.p.george@gmail.com 2017-06-14T07:18:23+00:00 urn:sha1:3bedff0b3cbb5ae9bc499f8ec0108c54f26fc87c These implementations are incorrect (eg f2d and d2f don't handle special values like 0.0) and proper versions can be provided by libgcc (or equivalent depending on the toolchain). libgcc is now linked with the stmhal port so that library will provide these functions from now on. lib/libm: Move Thumb-specific sqrtf function to separate file. 2016-11-03T01:26:32+00:00 Damien George damien.p.george@gmail.com 2016-11-03T01:26:32+00:00 urn:sha1:cd527bb324ade952d11a134859d38bf5272c165e This allows it to be used only when the hardware supports VFP instructions, preventing compile errors. lib/libm: Allow math funcs to be used by non-Thumb archs. 2015-12-18T21:05:44+00:00 Damien George damien.p.george@gmail.com 2015-12-18T21:05:44+00:00 urn:sha1:a67651406d4154cd5093884dea6ca0ca395d56db Requires addition of software implementation of sqrtf function. 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: 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.
