2021-07-25Remove redundant include headers.Yukihiro "Matz" Matsumoto
- stdlib.h - stddef.h - stdint.h - stdarg.h - limits.h - float.h
2021-07-10numeric.c: `self` should always be an integer in `__coerce_step_counter`.Yukihiro "Matz" Matsumoto
2021-07-10Update internal methods not to be listed in backtraces.Yukihiro "Matz" Matsumoto
- String#__lines - Array#__ary_eq - Array#__ary_cmp - Hash#__delete - Kernel#__case_eqq - Integer#__coerce_step_counter
2021-06-21numeric.c: add optional `ndigits` argument to rounding methods.Yukihiro "Matz" Matsumoto
- `truncate` - `floor` - `ceil` `round` already takes `ndigits`.
2021-06-15numeric.c: restore `fmt` argument for backward compatibility.Yukihiro "Matz" Matsumoto
`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.
2021-05-31numeric.c: fixed a silly bug related to pointer decrement.Yukihiro "Matz" Matsumoto
2021-05-30numeric.c: introduce `mrb_int_to_cstr()` to dump `mrb_int`.Yukihiro "Matz" Matsumoto
* refactor `mrb_integer_to_str()` * refactor `mrb_str_format()`
2021-05-26fmt_fp.c: move mruby specific `mrb_float_to_str` to `numeric.c`Yukihiro "Matz" Matsumoto
2021-05-21fmt_fp.c: remove `fmt` argument from `mrb_float_to_str()`.Yukihiro "Matz" Matsumoto
With major refactoring to prepare removing `snprintf(3) calls.
2021-05-17Global renaming regarding `integer` and `float`.Yukihiro "Matz" Matsumoto
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`
2021-05-17Rename `mrb_fixnum_to_str` to `mrb_integer_to_str`.Yukihiro "Matz" Matsumoto
2021-05-17Rename `mrb_flo_to_fixnum` to `mrb_float_to_integer`.Yukihiro "Matz" Matsumoto
2021-04-24numeric.c: remove duplicated definitions; #5421Yukihiro "Matz" Matsumoto
Following functions are defined in `mrblib/numeric.c`: - `Integer#ceil` - `Integer#floor` - `Integer#round` - `Integer#truncate`
2021-04-24numeric.c: fix errors from `MRB_NO_FLOAT`; close #5421Yukihiro "Matz" Matsumoto
2021-04-21numeric.c: update error messages in `int_pow`; ref #5420Yukihiro "Matz" Matsumoto
2021-04-21numeric.c: fix `int_pow` to detect integer overflow; fix #5420Yukihiro "Matz" Matsumoto
2021-04-16feat(CI): add the GitHub Super LinterJohn Bampton
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
2021-03-28numeric.c: function renaming.Yukihiro "Matz" Matsumoto
- `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.
2021-03-19complex.c: overhaul complex operators.Yukihiro "Matz" Matsumoto
- 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
2021-03-19rational.c: overhaul rational operators.Yukihiro "Matz" Matsumoto
- 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
2021-03-19numeric.c: avoid integer overflow; close #5384Yukihiro "Matz" Matsumoto
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.
2021-03-19`Float#divmod` with zero should cause `ZeroDivisionError`; #5384Yukihiro "Matz" Matsumoto
2021-03-18`Float::NAN/0` should be `Float::NAN`; ref a0b3378b3KOBAYASHI Shuji
#### 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 ```
2021-03-18numeric.c: float zero division should be infinity with sign kept; fix #5382Yukihiro "Matz" Matsumoto
2021-03-07bug(presym): Fix mrb_cmp declaration of <=> symbol for funcallRyan Lopopolo
2021-01-26Revert "Minimize the changes in #5277"Yukihiro "Matz" Matsumoto
This reverts commit dc51d89ac22acc60b9bfeed87115863565b74085.
2021-01-22Minimize the changes in #5277Yukihiro "Matz" Matsumoto
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.
2021-01-21Merge branch 'avoid-including-presym.inc-in-existing-header-files' of ↵Yukihiro "Matz" Matsumoto

2021-01-17Make `mrb_to_flo()` to convert objects, not integer, not float; #5268Yukihiro "Matz" Matsumoto
Thinking `Ratinal` and `Complex` in mind.
2021-01-11Avoid including `presym.inc` in existing header filesKOBAYASHI Shuji
Addressed an issue where existing programs linking `libmruby.a` could only be built by adding `<build-dir>/include` to compiler's include path.

- Integrate `Fixnum` and `Integer` - Remove `Integral` - `int / int -> int` - Replace `mrb_fixnum()` to `mrb_int()` - Replace `mrb_fixnum_value()` to `mrb_int_value()`. - Use `mrb_integer_p()` instead of `mrb_fixnum_p()`
