2021-03-24complex.c: use `mrb_num_div_flo` to avoid copying function.Yukihiro "Matz" Matsumoto
This change relies that `mrb_num_div_flo` does not use `mrb` inside.
2021-03-24complex.rb: unary plus (`+@`) to return self avoiding copying.Yukihiro "Matz" Matsumoto
2021-03-24complex.c: implement `Complex` addition and subtraction in C.Yukihiro "Matz" Matsumoto
2021-03-24complex.c: override float division to support `Complex`.Yukihiro "Matz" Matsumoto
2021-03-24Use `div_flo` (copy of `mrb_num_div_flo`) for float division.Yukihiro "Matz" Matsumoto
2021-03-24Use `mrb_num_div_flo` for float division.Yukihiro "Matz" Matsumoto
This function handles zero division properly. Also fixed bugs that multiply numbers instead of division.
2021-03-24Fix infinite recursive call bugs in integer division.Yukihiro "Matz" Matsumoto
2021-03-24complex.c: implement `Complex#/` and `#quo` in C.Yukihiro "Matz" Matsumoto
2021-03-24complex.c: implement `Complex#*` in C.Yukihiro "Matz" Matsumoto
2021-03-24rational.rb: avoid 'NaNi` representation.Yukihiro "Matz" Matsumoto
Use `NaN*i` as CRuby does.
2021-03-22Use global defines for `Rational` and `Complex`.Yukihiro "Matz" Matsumoto
2021-03-21complex.c: define `Complex#==` in C.Yukihiro "Matz" Matsumoto
This change also fixes the error caused by `rational.c` that calls `mrb_complex_eq()`, which had been undefined.
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
2021-02-26Use `MRB_SYM()` more extensively.Yukihiro "Matz" Matsumoto
2021-02-05Add a few new API for complex access.Yukihiro "Matz" Matsumoto
2021-02-05Refactor method overriding.Yukihiro "Matz" Matsumoto
* Use `class_eval` instead of `instance_eval`. * Reduce `class_eval` calls * define `Numeric#i` * undefine `Complex#i`
2021-02-05Add `Complex#to_c` method.Yukihiro "Matz" Matsumoto
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.
2021-01-11Avoid 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.
2020-10-12Silence warnings from implicit integer conversions.Yukihiro "Matz" Matsumoto
Caused from combination of `mrb_int`, `int` and `size_t`..
2020-10-12Integrate `Fixnum` class into `Integer` classdearblue
* 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.
2020-10-12Update tests for integer division.Yukihiro "Matz" Matsumoto
2020-10-12Rename float configuration option names.Yukihiro "Matz" Matsumoto
- `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.
2020-10-12Use functions that take symbols to reduce string litrals in C.Yukihiro "Matz" Matsumoto
2020-06-20Add `mrb_get_arg1()` that retrieves single (and only) argument.Yukihiro "Matz" Matsumoto
`mrb_get_arg1()` raises `ArgumentError` if the method does not receive one argument. And replaces all `mrb_get_args(mrb, "o", &arg)` by the new function.
2020-06-20Symbolify saved alias name to improve performance.Yukihiro "Matz" Matsumoto
2019-12-15Drop dependencies from `mruby-complex` to some gemsKOBAYASHI Shuji
2019-08-09Avoid overflow and underflow in Complex#/Ray Chason
2019-08-08Implement Complex#abs in terms of Math.hypotRay Chason
Math.hypot avoids premature overflow and underflow
2019-08-05Use new specifiers/modifiers of `mrb_vfromat()`KOBAYASHI Shuji
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. ------------+-------------------+-------------------+-------- BINARY | BEFORE (5116789a) | AFTER (This PR) | RATIO ------------+-------------------+-------------------+-------- mruby | 593416 bytes | 593208 bytes | -0.04% libmruby.a | 769048 bytes | 767264 bytes | -0.23% ------------+-------------------+-------------------+-------- BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613, so I put it back.
2019-07-30Refine message to `skip` in nested `assert`KOBAYASHI Shuji
- I think "Info" is used only to `skip`, so change to "Skip". - Changed the default value of `assert` and specify the argument explicitly at the caller of `assert` because it is unnatural "Assertion failed" is output even though the assertion doesn't fail. == Example: def assert_foo(exp, act) assert do assert_equal exp[0], act[0] assert_equal exp[1], act[1] end end def assert_bar(exp, act) assert do skip end end def assert_baz(exp, act) assert do assert_equal exp, act assert_bar exp, act end end assert 'test#skip_in_nested_assert' do assert_baz 1, 1 end === Before this patch: ?.. Info: test#skip_in_nested_assert (core) - Assertion[1] Info: Assertion failed (core) - Assertion[1-2] Skip: Assertion failed (core) Total: 3 OK: 2 KO: 0 Crash: 0 Warning: 0 Skip: 1 === After this patch: ??? Skip: test#skip_in_nested_assert (core) - Assertion[1] Skip: assert (core) - Assertion[1-2] Skip: assert (core) Total: 3 OK: 0 KO: 0 Crash: 0 Warning: 0 Skip: 3
2019-07-24Call `MRB_SET_INSTANCE_TT` for `Complex` and `Rational`.Yukihiro "Matz" Matsumoto
2019-07-22Check conflicts with `Complex` and `MRB_WITHOUT_FLOAT`; ref #4576Yukihiro "Matz" Matsumoto
The Complex class needs `mrb_float` so that it does not work with `MRB_WITHOUT_FLOAT` anyway.
2019-07-18Avoid making top-level `env` in initialization code; ref #4581Yukihiro "Matz" Matsumoto
2019-07-13Resolve ambiguous argument warning.Yukihiro "Matz" Matsumoto
2019-06-29Use nested `assert`dearblue
2019-06-05Fix not frozen in `Complex` method by `RData`dearblue
Object allocation was separated, and initialization was made common.
2019-06-05Fix memory leak in `Complex` method by `RData`dearblue
If `Data_Wrap_Struct()` raises a `NoMemoryError` exception, it will leak memory if it does `mrb_malloc()` first.

2019-05-21Remove `Complex(string)` complex generation.Yukihiro "Matz" Matsumoto
