Bug #5490

Bignum#div(0.0) raises FloatDomainError instead of ZeroDivisionError
Description
Bignum#div(0.0) raises FloatDomainError. Everything else raises ZeroDivisionError.
This should be fixed in both 1.9.3 and 2.0.0.

Is this going to be backported to 1.9? The RubySpecs were changed with a ruby_version_is guard, which would be incorrect if this is considered a bug. If it's not considered a bug, why not?
Thanks,
Brian
