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

Hi
Thanks for your reply
Sijo
Integer is the superclass, Fixnum is more appropriate.

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
