I'm having he same problem. Simple program (see attached temp.rb) to
calculate fahrenheit/celsius conversions. to calc. the fahrenheit
where:

f = 1.8 * (temp + 32)

The program works fine but there is a response

warning: Float 1.8 out of range.

NOBODY has answered this question as I have googled, yahoo'd and binged
this questions and the closest I get is what ide to use.

I cannot reproduce the problem on my Linux box. strtod() on Windows
might be broken.

Which version of Ruby are you using? I am unable to duplicate on either the
1.8.6 or 1.8.7 Windows Ruby from http://rubyinstaller.org/
