py: Add MICROPY_FLOAT_CONST macro for defining float constants.

2016-11-03T01:33:01+00:00

All float constants in the core should use this macro to prevent unnecessary creation of double-precision floats, which makes code less efficient.

all: Remove 'name' member from mp_obj_module_t struct.

2016-09-21T14:23:16+00:00

One can instead lookup __name__ in the modules dict to get the value.

py/objfloat, py/modmath: Ensure M_PI and M_E defined.

2016-05-12T12:28:45+00:00

In some compliation enviroments (e.g. mbed online compiler) with strict standards compliance, does not define constants such as M_PI. Provide fallback definitions of M_E and M_PI where needed.

py: Change type signature of builtin funs that take variable or kw args.

2016-01-11T00:49:27+00:00

With this patch the n_args parameter is changed type from mp_uint_t to size_t.

py/modmath: Add domain error checking to sqrt, log, log2, log10.

2015-12-12T15:12:54+00:00

These functions will raise 'ValueError: math domain error' on invalid input.

py: Add MP_ROM_* macros and mp_rom_* types and use them.

2015-11-29T14:25:04+00:00

py/modmath: Make log2, log10 and hyperbolic funcs be SPECIAL_FUNCTIONS.

2015-11-17T14:10:13+00:00

Will be included only when MICROPY_PY_MATH_SPECIAL_FUNCTIONS is enabled. Also covers cmath module (but only log10 is there at the moment).

py/modmath: Don't create symbol entry for expm1() if not needed.

2015-11-13T22:55:54+00:00

py/modmath: Make expm1() be in MICROPY_PY_MATH_SPECIAL_FUNCTIONS.

2015-11-13T22:46:52+00:00

unix/mpconfigport: Move log2() definition to modmath.c.

2015-11-13T13:24:48+00:00

It's safer to define it where it's used, defining it for all source files may lead to hard to diagnose conflicts in corner cases.
