An integer number can range from -2 30 to 2 30-1 or -2 62 to 2 62-1. Integers within this range are objects of class Fixnum and integers outside this range are stored in objects of class Bignum.

to_i converts a string to an integer, and to_f converts a string to a float. "5".to_i "55.5".to_i "55.5".to_f Let’s demonstrate this by creating a small program that prompts for two numbers and displays the sum. If the object is a string & the contents of the string strictly conform to a valid numeric representation in Ruby this method will return an Integer. Raises ArgumentError if invalid format. If the object isn’t a string it will try to call to_int, then to_i. No security, no password. Other people might choose the same nickname.
