I guess it is never coming out of your while loop. Have a look at the Rails Guide on debugging to find out how to break into code using ruby_debug and see what is going on. Also you could try putting some write statements in the function to see what is happening. Hint: It may not help but what happens if you try squareroot(55.0)? If that helps make sure you understand why (using debug or print statements). Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
