Feature #12005
Updated by naruse (Yui NARUSE) almost 8 years ago
CRuby has two `Integer` classes, `Fixnum` and `Bignum`.
But it is implementation detail.
They should be seen as a single class `Integer` like `Flonum`.
## Compatibility note
* Q: How do I check whether Fixnum and Bignum are unified or not?
* A: check RUBY_INTEGER_UNIFICATION macro
