Yukihiro "Matz" Matsumoto b70fd09f47 Revert "numeric.c: simplifies int_mod definition." 
This reverts commit 3738d62a86.
The change changed the behavior with floating point numbers.

Yukihiro "Matz" Matsumoto 3738d62a86 numeric.c: simplifies int_mod definition. 2021-08-03 13:14:23 +09:00
Yukihiro "Matz" Matsumoto b9d2b47f16 Replace mrb_fixnum_value() with mrb_int_value(). 
Use `mrb_fixnum_value()` only when you are absolutely sure that the
value is within `Fixnum` range, i.e. 31 bits signed integer at least.
 2021-08-03 13:00:11 +09:00
Yukihiro "Matz" Matsumoto 23e7cb41e5 Replace fixnum references with int. 
The `Fixnum` class is no longer provided by `mruby`.

Yukihiro "Matz" Matsumoto 8416e706ba numeric.c: add optional ndigits argument to rounding methods. 
- `truncate`
- `floor`
- `ceil`

`round` already takes `ndigits`.

Yukihiro "Matz" Matsumoto 7c8a91ff5a numeric.c: restore fmt argument for backward compatibility. 
`mrb_float_to_str()` used to take `fmt` argument. We thought no one used
the function, and OK to remove the argument. But at least `mruby-redis`
gem used the function.
 2021-06-15 16:19:16 +09:00
Yukihiro "Matz" Matsumoto cf2e78de44 numeric.c: fixed a silly bug related to pointer decrement. 2021-05-31 02:59:33 +09:00

* refactor `mrb_integer_to_str()`
* refactor `mrb_str_format()`
 2021-05-30 08:15:51 +09:00
Yukihiro "Matz" Matsumoto c019d8d34d fmt_fp.c: move mruby specific mrb_float_to_str to numeric.c 2021-05-26 17:29:18 +09:00
Yukihiro "Matz" Matsumoto fa29bb3bb4 fmt_fp.c: remove fmt argument from mrb_float_to_str(). 
With major refactoring to prepare removing `snprintf(3) calls.
 2021-05-21 08:13:38 +09:00
Yukihiro "Matz" Matsumoto 5eebbd7df2 Global renaming regarding integer and float. 
Consistent number conversion function names:
* `mrb_value` to immediate (C) value
  * `mrb_int()` -> `mrb_as_int()`
  * `mrb_to_flo()` -> `mrb_as_float()`
* `mrb_value` to `mrb_value` (converted)
  * `mrb_to_int()'
  * `mrb_Integer()` - removed
  * `mrb_Float()` -> `mrb_to_float`

Consistent function name (avoid `_flo` suffix):
* `mrb_div_flo()` -> `mrb_div_float`

John Bampton 9d32d440eb feat(CI): add the GitHub Super Linter 
The GitHub Super Linter is a more robust and better supported
tool than the current GitHub Actions we are using.

Running these checks:

ERROR_ON_MISSING_EXEC_BIT: true
VALIDATE_BASH: true
VALIDATE_BASH_EXEC: true
VALIDATE_EDITORCONFIG: true
VALIDATE_MARKDOWN: true
VALIDATE_SHELL_SHFMT: true
VALIDATE_YAML: true

https://github.com/marketplace/actions/super-linter
https://github.com/github/super-linter

Added the GitHub Super Linter badge to the README.

Also updated the pre-commit framework and added
more documentation on pre-commit.

Added one more pre-commit check: check-executables-have-shebangs

Added one extra check for merge conflicts to our
GitHub Actions.

EditorConfig and Markdown linting.

Minor grammar and spelling fixes.

Update linter.yml

Yukihiro "Matz" Matsumoto a5244b02c5 numeric.c: function renaming. 
- `mrb_num_div_int(mrb,x,y)` -> `mrb_div_int(mrb,x,y)`
- `mrb_num_div_flo(mrb,x,y)` -> `mrb_div_flo(x,y)`

They are internal function not supposed to be used outside of the core.

Yukihiro "Matz" Matsumoto d3184e4a6d complex.c: overhaul complex operators. 
- define `MRB_TT_COMPLEX`
- change object structure (`struct RComplex`)
- add memory management for `MRB_TT_COMPLEX`
- avoid operator overloading as much as possible
- as a result, performance improved a log
- should work with and without `Rational` defined
 2021-03-19 10:37:10 +09:00
Yukihiro "Matz" Matsumoto 08f9d5bab5 rational.c: overhaul rational operators. 
- define `MRB_TT_RATIONAL`
- change object structure (`struct RRational`)
- add memory management for `MRB_TT_RATIONAL`
- avoid operator overloading as much as possible
- implement division overloading in C
- as a result, performance improved a lot
 2021-03-19 10:37:10 +09:00
Yukihiro "Matz" Matsumoto eb07030308 numeric.c: avoid integer overflow; close #5384 
Since `mruby` does not have `Bignum`, `Float#divmod` could overflow, so
it will return `Float` values when the divided value does not fit in
`mrb_int`. This behavior will be changed when `Bignum` is introduced to
`mruby` in the future.

Yukihiro "Matz" Matsumoto 087e1719e4 Float#divmod with zero should cause ZeroDivisionError; #5384 2021-03-19 07:13:19 +09:00
KOBAYASHI Shuji 6731f935cc Float::NAN/0 should be Float::NAN; ref a0b3378b3 
#### Before this patch:

```console
$ bin/mruby -e 'p(Float::NAN/0)'
Infinity
```

#### After this patch (same as Ruby):

```console
$ bin/mruby -e 'p(Float::NAN/0)'
NaN
```

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.

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.
