Hi I have string say str1 when i use
res=str1.to_i puts res.class
The result i get is Fixnum. Actually does to_i convert str1 to Integer or Fixnum?So why i did not get result as Integer?

Hi Sijo,
Fixnum is nothing but integer. what you call integer in sql fixnum in ruby.
Thanks Saravanan

123.class => Fixnum 12345678901234567890.class => Bignum Fixnum.superclass => Integer Bignum.superclass => Integer
Integer is a class in Ruby with 2 subclasses (Fixnum and Bignum). Fixnum is the class of integers with a small magnitude. These are represented internally using a type your operating system can manipulate. Bignum is the class of all integers with a magnitude too big to fit into that type. Bignum can be used for arbitrary sized integers.
Ruby uses whichever class it needs to behind the scenes to perform arithmetic. You don't need to worry about it because:
123.kind_of? Integer => true 12345678901234567890.kind_of? Integer => true
Integer is the superclass, Fixnum is more appropriate.
