12345.class returning 'Integer' not 'Fixnum' in Ruby

Question

On the Ruby tutorials I'm watching when you enter a number with .class it returns either Bignum or Fixnum.

When I do this I get Integer instead:

12345.class
#=> Integer

I'm using irb in the command line on a mac. Why does the above not return Fixnum like it does in the tutorials?

Answer 1

It depends on the Ruby version. From Ruby 2.4.0 we have just Integers, no more Fixnums and Bignums distinction
