This works fine for me and returns values that I am expecting.  Changing 
it slightly to:
x = (Float(x) rescue Integer(x) rescue 0).to_f
gives me the Float value I was looking for.  I can live with this, just 
part of learning a new language is learning when something will not work 
the way you expect and how to work around it.
Thank you for the code.  I am still learning how to use exceptions.
