Sorry I didn't follow this up for so long, Range#step does take float 
values too, as shown by:

irb(main):006:0> RUBY_VERSION
=> "2.0.0"
irb(main):007:0> (0.0..3.0).step(1.1){|i| puts i}
0.0
1.1
2.2
=> 0.0..3.0

It's inconsistent and needs fixing either to actually only accept 
Integers or accept floats correctly.
