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 7ddd85f933 lib/libm: Remove unused definition of "one". 2016-06-25 22:30:40 +01:00
Damien George 873853f1a8 lib/libm: Format code to pass gcc v6.1.1 warning.
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.

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 1559a97810 py: Add builtin round function.
Addresses issue #934.

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.
