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 ```

2021-01-26Revert "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.

2021-01-17Fix `int_quo` to do float division; fix #5268Yukihiro "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.

Where fixnum overflow can happen.
2020-10-12Reorganize `Integer` system.Yukihiro "Matz" Matsumoto
- 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()`
2020-10-12Make division by zero cause `ZeroDivisionError`.Yukihiro "Matz" Matsumoto
As described in ISO 15.2.30.
2020-10-12Rename `MRB_TT_FIXNUM` to `MRB_TT_INTEGER`.Yukihiro "Matz" Matsumoto
We still have `#define MRB_TT_FIXNUM MRB_TT_INTEGER` for compatibility.
2020-10-12Always add trailing `.0` in `Float#inspect`; ref #4225KOBAYASHI Shuji
Trailing `.0` is removed from `Float#to_s` and `Float#inspect` at 9d08025b. However, I think the more human-readable format is better for `Float#inspect`. For example, in the `Float#to_s` format, the failure message is not well understood when testing values including types by `eql?` (e.g. `Numeric#step` test). ```ruby assert "example" do exp = 1.0 act = 1 assert_operator(exp, :eql?, act) #=> Expected 1 to be eql? 1. end ```
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.
2020-10-12Rename 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 `mrb_funcall_id()` extensively.Yukihiro "Matz" Matsumoto
Except for support files e.g. `mruby-test/driver.c`, which are not target of symbol collection via `rake gensym`.

`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.
