Derek Prior created JRUBY-6557:
----------------------------------
Summary: Range#step does not accept float steps with integer ranges
Key: JRUBY-6557
URL: https://jira.codehaus.org/browse/JRUBY-6557
Project: JRuby
Issue Type: Bug
Components: Ruby 1.8.7
Affects Versions: JRuby 1.6.7
Reporter: Derek Prior
Priority: Minor
# MRI (1.8.7-p352, 1.9.2-p290):
(0..2).step(0.5).map {|x| x}
=> [0.0, 0.5, 1.0, 1.5, 2.0]
# JRuby 1.6.7:
(0..2).step(0.5).map {|x| x}
=> ArgumentError: step can't be 0.
# JRuby 1.6.7 --1.9
(0..2).step(0.5).map {|x| x}
=> [0.0, 0.5, 1.0, 1.5, 2.0]
It seem to coerce the float to an int. I believe this fails the following
rubyspec:

The workaround is to provide the range also as a float.
