Damien George cd527bb324 lib/libm: Move Thumb-specific sqrtf function to separate file.
This allows it to be used only when the hardware supports VFP
instructions, preventing compile errors.

Damien George a67651406d lib/libm: Allow math funcs to be used by non-Thumb archs.
Requires addition of software implementation of sqrtf function.

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.

Paul Sokolovsky 8a2cc1c7e4 stmhal: Add fake implementation of __aeabi_f2lz().
To make mp_obj_new_int_from_float() somehow work.

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!).

Damien George 8594ce2280 py: Implement divmod, % and proper // for floating point.
Tested and working on unix and pyboard.

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.

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.
