Yukihiro "Matz" Matsumoto d9bf3235d2 mruby-math/math.c: avoid mrb_get_args() if possible 
When a method takes single argument, we can use lighter `mrb_get_arg1()`
instead of `mrb_get_args()`.

Yukihiro "Matz" Matsumoto 9c5dc42e59 small cosmetic changes. 
I prefer `i++` style unless absolutely necessary.
This commit is an addition to 41e4148.

Yukihiro "Matz" Matsumoto 9f47f11abd math.c: update prototype style. 2022-09-05 07:30:12 +09:00
dearblue 5a57602860 Organize the include of header files 
- `#include <math.h>` is done in `mruby.h`.
  Eliminate the need to worry about the `MRB_NO_FLOAT` macro.

- Include mruby header files before standard header files.
  If the standard header file is already placed before `mruby.h`, the standard header file added in the future tends to be placed before `mruby.h`.

This change should some reduce the chances of macros that must be defined becoming undefined in C++ or including problematic header files in a particular mruby build configuration.

Yukihiro "Matz" Matsumoto 5c804cf68f Remove redundant include headers.

Yukihiro "Matz" Matsumoto 17ecf14511 Revert "Minimize the changes in #5277" 
This reverts commit dc51d89ac2.
 2021-01-26 10:57:07 +09:00
Yukihiro "Matz" Matsumoto dc51d89ac2 Minimize the changes in #5277 
Instead of including `mruby/presym.h` everywhere, we provided the
fallback `mruby/presym.inc` under `include/mruby` directory, and specify
`-I<build-dir>/include` before `-I<top-dir>/include` in `presym.rake`.
So even when someone drops `-I<build-dir>/include` in compiler options,
it just compiles without failure.
 2021-01-22 18:38:53 +09:00
KOBAYASHI Shuji 90b53f4c29 Avoid including presym.inc in existing header files 
Addressed an issue where existing programs linking `libmruby.a` could only
be built by adding `<build-dir>/include` to compiler's include path.

Yukihiro "Matz" Matsumoto 2e30c68562 Move MRB_NO_FLOAT detection in mruby-math; #5185 2020-11-24 20:43:56 +09:00
Yukihiro "Matz" Matsumoto 08f61db6ee Skip some Math.atan2() tests. 
Linux `atan2(3)` man page says:

```
If  y is positive infinity (negative infinity) and x is positive infinity,
+pi/4 (-pi/4) is re‐ turned.
```

But on Microsoft VC/MinGW, `atan2()` returns `NaN` if either of
arguments is infinite. So we skip those tests on the platforms.

dearblue 80fe9838d2 Integrate Fixnum class into Integer class 
* The `Fixnum` constant is now an alias for the `Integer` class.
* Remove `struct mrb_state::fixnum_class` member.
  If necessary, use `struct mrb_state::integer_class` instead.

Yukihiro "Matz" Matsumoto 8a87549315 Rename float configuration option names. 
- `MRB_WITHOUT_FLOAT` => `MRB_NO_FLOAT`
- `MRB_USE_FLOAT` => `MRB_USE_FLOAT32`

The former is to use `USE_XXX` naming convention. The latter is to make
sure `float` is 32bit float and not floating point number in general.

KOBAYASHI Shuji 334afb167c Use new specifiers/modifiers of mrb_vfromat() 
The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in
my environment than before the introduction of new specifiers/modifiers
(5116789a) with this change.

Tomoyuki Sahara 116f75a8ce "spec.author" is better for single-author gems. 
"spec.author=" expects a String represents a single author.
"spec.authors=" expects an Array which is a list of multiple authors.
