== is meaningless with floats.
The previous issue ( the value before the excluded end of the range
not being reached) was most likely the result of guarding against
this:
(1.0...128.4).step(18.2).to_a
=> [1.0, 19.2, 37.4, 55.599999999999994, 73.8, 92.0, 110.19999999999999, 128.4]
I am quite sure that the 128.4 are not the same.
Still Ruby does not display the difference so the result is quite confusing.
Thanks
