2017-07-31all: Use the name MicroPython consistently in commentsAlexander Steffen
There were several different spellings of MicroPython present in comments, when there should be only one.
2017-06-14lib/libm/math: Remove implementations of float conversion functions.Damien George
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.
2017-05-31lib/libm: Use isfinite instead of finitef, for C99 compatibility.Damien George
2017-03-24lib/libm: Add implementation of nearbyintf, from musl-1.1.16.Damien George
2016-11-03lib/libm: Move Thumb-specific sqrtf function to separate file.Damien George
This allows it to be used only when the hardware supports VFP instructions, preventing compile errors.
2016-06-25lib/libm: Remove unused definition of "one".Damien George
2016-06-25lib/libm: Format code to pass gcc v6.1.1 warning.Damien George
gcc 6.1.1 warns when indentation is misleading, and in this case the formatting of the code really is misleading. So adjust the formatting to be clear of the meaning of the code.
2015-12-18lib/libm: Allow math funcs to be used by non-Thumb archs.Damien George
Requires addition of software implementation of sqrtf function.
2015-02-22lib/libm: Add implementations of erf, erfc, lgamma, tgamma.Damien George
2015-01-22lib/libm: Add frexp and modf functions; use in stmhal; add tests.Damien George
Addresses issue #1081.
2014-12-30stmhal: Add fake implementation of __aeabi_f2lz().Paul Sokolovsky
To make mp_obj_new_int_from_float() somehow work.
2014-12-18lib/libm: Add acosh, asinh, atanh, tan; get working with stmhal.Damien George
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!).
2014-10-31py: Add builtin round function.Damien George
Addresses issue #934.
2014-09-13py: Implement divmod, % and proper // for floating point.Damien George
Tested and working on unix and pyboard.
2014-09-11py and libm: Add asinf,acosf; print higher precision for float.Damien George
Also use less stack space when printing single precision float. Addition of asinf and acosf addresses issue #851.
2014-08-29lib, libm: Add back dummy definition of tanf.Damien George
2014-08-29lib: Add lib and libm, moving current files from stmhal.Damien George
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.
