6911b4bc82 test_cdhash: refactor change class 
It is now strange to test Complex in a class named Rational_Test.

cc0dc67bbb cdhash_cmp: can also take complex 
There are complex literals `123i`, which can also be a case condition.

2bc293e899 cdhash_cmp: can take rational literals 
Rational literals are those integers suffixed with `r`.  They tend to
be a part of more complex expressions like `123/456r`, but in theory
they can live alone.  When such "bare" rational literals are passed to
case-when branch, we have to take care of them.  Fixes [Bug #17854]

85bcd2b35f bignum.c: Bignum#fdiv avoids double division when divisor is bignum 
`Rational(int, bignum).to_f` sometimes returned a wrong result because
`Bignum#div` casted its divisor to double.  [Bug #14637] [ruby-core:86330]

0dc74b94c2 Add exception: keyword in Kernel#Rational() 
Support `exception:` keyword argument in `Kernel#Rational()`.
If `exception:` is `false`, `Kernel#Rational()` returns `nil` if the given
value cannot be interpreted as a rational value.
The default value of `exception:` is `true`.
This is part of [Feature #12732].
