Damien George d8d4e4dfbe py/modmath: Convert log2 macro into a function.
So that a pointer to it can be passed as a pointer to math_generic_1.  This
patch also makes the function work for single and double precision floating
point.

Damien George 25e140652b py/modmath: Add full checks for math domain errors.
This patch changes how most of the plain math functions are implemented:
there are now two generic math wrapper functions that take a pointer to a
math function (like sin, cos) and perform the necessary conversion to and
from MicroPython types.  This helps to reduce code size.  The generic
functions can also check for math domain errors in a generic way, by
testing if the result is NaN or infinity combined with finite inputs.

The result is that, with this patch, all math functions now have full
domain error checking (even gamma and lgamma) and code size has decreased
for most ports.  Code size changes in bytes for those with the math module
are:

   unix x64:  -432
unix nanbox:  -792
      stm32:   -88
    esp8266:   +12

Tests are also added to check domain errors are handled correctly.

Damien George 0102ee092b py: Change obsolete "///" comment formatting to normal comments.
This comment style is no longer used because the docs are written by hand,
not generated.

Alexander Steffen 55f33240f3 all: Use the name MicroPython consistently in comments
There were several different spellings of MicroPython present in comments,
when there should be only one.

Damien George 6b8b56f859 py/modmath: Check for zero division in log with 2 args. 2017-07-04 02:15:11 +10:00
Damien George 48d867b4a6 all: Make more use of mp_raise_{msg,TypeError,ValueError} helpers. 2017-06-15 11:54:41 +10:00
Damien George febeff4af4 py/modmath: Allow trunc/ceil/floor to return a big int if necessary.
Previous to this patch, if the result of the trunc/ceil/floor functions
overflowed a small int, or was inf or nan, then a garbage value was
returned.  With this patch the correct big-int is returned if necessary,
and exceptions are raised for inf or nan.

Damien George 561844f3ba py: Add MICROPY_FLOAT_CONST macro for defining float constants.
All float constants in the core should use this macro to prevent
unnecessary creation of double-precision floats, which makes code less
efficient.

Damien George 93c4a6a3f7 all: Remove 'name' member from mp_obj_module_t struct.
One can instead lookup __name__ in the modules dict to get the value.

Colin Hogben a896951a9a py/objfloat, py/modmath: Ensure M_PI and M_E defined.
In some compliation enviroments (e.g. mbed online compiler) with
strict standards compliance, <math.h> does not define constants such
as M_PI.  Provide fallback definitions of M_E and M_PI where needed.

Damien George 4b72b3a133 py: Change type signature of builtin funs that take variable or kw args.
With this patch the n_args parameter is changed type from mp_uint_t to
size_t.

Michael Buesch 17298af61e py/modmath: Add domain error checking to sqrt, log, log2, log10.
These functions will raise 'ValueError: math domain error' on invalid
input.

Damien George cbf7674025 py: Add MP_ROM_* macros and mp_rom_* types and use them. 2015-11-29 14:25:04 +00:00
Damien George a24eafacc9 py/modmath: Make log2, log10 and hyperbolic funcs be SPECIAL_FUNCTIONS.
Will be included only when MICROPY_PY_MATH_SPECIAL_FUNCTIONS is enabled.

Also covers cmath module (but only log10 is there at the moment).

Paul Sokolovsky 863d4cd862 py/modmath: Don't create symbol entry for expm1() if not needed. 2015-11-14 00:55:54 +02:00
Paul Sokolovsky 0d6116d86b py/modmath: Make expm1() be in MICROPY_PY_MATH_SPECIAL_FUNCTIONS. 2015-11-14 00:46:52 +02:00
Paul Sokolovsky 6d1eabfeaa unix/mpconfigport: Move log2() definition to modmath.c.
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.

Paul Sokolovsky 1b586f3a73 py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming. 2015-10-11 15:18:15 +03:00
Damien George 6f49520042 py: Implement second arg for math.log (optional value for base). 2015-06-13 22:35:25 +01:00
Damien George 5cbeacebdb py: Make math special functions configurable and disabled by default.
The implementation of these functions is very large (order 4k) and they
are rarely used, so we don't enable them by default.

They are however enabled in stmhal and unix, since we have the room.

Damien George 3b603f29ec Use MP_DEFINE_CONST_DICT macro to define module dicts.
This is just a clean-up of the code.  Generated code is exactly the
same.

MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET
MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY
MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE

Damien George 04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

Damien George 8b0535e23f py: Change module globals from mp_map_t* to mp_obj_dict_t*.
Towards addressing issue #424.

Had a small increase to ROM usage (order 60 bytes).

Damien George df6567e634 Merge map.h into obj.h.
Pretty much everyone needs to include map.h, since it's such an integral
part of the Micro Python object implementation.  Thus, the definitions
are now in obj.h instead.  map.h is removed.

Damien George caac542b23 Proper support for registering builtin modules in ROM.
