Yukihiro "Matz" Matsumoto a127ded486 Fix warning from VC regarding implicit int conversion. 2020-10-12 18:20:17 +09:00
Yukihiro "Matz" Matsumoto fe3c3bb661 Made Rational overhaul. 
- Implement `Rational()` in `C`.
- Use `float` to `rational` conversion function taken from:
  https://rosettacode.org/wiki/Convert_decimal_number_to_rational#C

Yukihiro "Matz" Matsumoto 01dbbcd553 Handle integer overflow in rational_s_new. 2020-10-12 18:20:05 +09:00
Yukihiro "Matz" Matsumoto 5134031e18 Use mrb_int_value() instead of mrb_fixnum_value(). 
Where fixnum overflow can happen.

Yukihiro "Matz" Matsumoto 2b188ed8a1 Reorganize Integer system. 
- 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()`

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 44381f0a0c Refine message to skip in nested assert 
- 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

In that case, to be switched implementation with `RData`.

It is based to "complex".

Consider a Numreic class like `Complex` that does not have `<=>` but `==`
works (`0i == 0r` is `true`).

KOBAYASHI Shuji 3b46831da8 Move **,/,quo,div and comparison methods to Integral from Numeric 
Having these methods in Numeric can get in the way of creating subclasses of
Numeric because they only support Fixnum and Float.

Yukihiro "Matz" Matsumoto ace0d3949b Support MRB_WITHOUT_FLOAT. 
I assume there's no realistic usage of `Rational` with
`MRB_WITHOUT_FLOAT`. But just for consistency.

`float op rational` should return `float`, since float is an inexact
value.
