Subject: Re: Is 2.0 Integer or Float?

Hope the following helps:

irb(main):001:0> 2.0.class
=> Float
irb(main):002:0> 2.class
=> Fixnum
irb(main):003:0> 2.0.is_a?(Float)
=> true
irb(main):004:0> 2.0.is_a?(Fixnum)
=> false
irb(main):005:0> 2.is_a?(Float)
=> false
irb(main):006:0> 2.is_a?(Fixnum)
=> true
