Damien George	a67651406d	lib/libm: Allow math funcs to be used by non-Thumb archs. ... Requires addition of software implementation of sqrtf function.	2015-12-18 21:05:44 +00:00
Damien George	9ab94c468c	lib/libm: Add implementations of erf, erfc, lgamma, tgamma.	2015-02-22 14:47:11 +00:00
Damien George	6d1f5070ce	lib/libm: Add frexp and modf functions; use in stmhal; add tests. ... Addresses issue #1081.	2015-01-22 13:48:29 +00:00
Paul Sokolovsky	8a2cc1c7e4	stmhal: Add fake implementation of __aeabi_f2lz(). ... To make mp_obj_new_int_from_float() somehow work.	2014-12-30 00:52:41 +02:00
Damien George	f04329e93b	lib/libm: Add acosh, asinh, atanh, tan; get working with stmhal. ... 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!).	2014-12-18 14:44:02 +00:00
Damien George	8594ce2280	py: Implement divmod, % and proper // for floating point. ... Tested and working on unix and pyboard.	2014-09-13 18:43:09 +01:00
Damien George	20beff9ae3	py and libm: Add asinf,acosf; print higher precision for float. ... Also use less stack space when printing single precision float. Addition of asinf and acosf addresses issue #851.	2014-09-11 22:24:45 +01:00
Damien George	4d3fc46326	lib, libm: Add back dummy definition of tanf.	2014-08-29 23:24:00 +01:00
Damien George	8707ea3421	lib: Add lib and libm, moving current files from stmhal. ... 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.	2014-08-29 22:42:26 +01:00
