Yukihiro "Matz" Matsumoto db8368fa86 numeric.c: remove bit operations methods from Float class; #6197 
mruby used to use float numbers for overflown integers before we
implemented big integers. Now we don't need bit operations for float
numbers anymore. Also removed tests for shift operations for float
numbers.

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 1974aa0f72 Update Float#to_s to keep trailing zero as CRuby does; ref 68cebb6 2020-11-21 14:38:13 +09:00
KOBAYASHI Shuji 8bd1bc47b3 Always add trailing .0 in Float#inspect; ref #4225 
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
  ```

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.

Yukihiro "Matz" Matsumoto 9d08025b8b Revert part of #4225 
Since in mruby, Integer and Float interchange frequently (mostly on
overflow), so adding explicit `.0` can cause problems sometimes.

For example:

https://github.com/pepabo/mruby-msd/pull/13
https://github.com/mattn/mruby-json/pull/42

KOBAYASHI Shuji 9f081183d2 Improve compatibility to CRuby for Float#to_s 
Bfore:

  Float::INFINITY.to_s  #=> "inf"
  50.0.to_s             #=> "50"
  1e20.to_s             #=> "1e+20"

After / CRuby:

  Float::INFINITY.to_s  #=> "Infinity"
  50.0.to_s             #=> "50.0"
  1e20.to_s             #=> "1.0e+20"
