I didn't realize the difference between Float() and .to_f.  Thanks for 
the suggestion.

The user is still aware if they entered an incorrect string, since they 
are entering it into a GUI textbox, and the string cleaning is done 
after each character is entered.  Thus, if they try to enter a misplaced 
+ sign or another bad character, they won't see it appear in the 
textbox, which should cause them to notice it.
