How to get value of Integer object in Ruby

Question

I am trying to implement Integer#times, but don't know how to know the value of an Integer object. So I am doing it like this:

class Integer
  def times
    n = (self.next) -1
    x = 1
    while x <= n
      yield(x)
      x += 1
    end
  end
end

I am using (self.next) -1 to get the value of the object:) I know it is not the right way of doing it. How to get the value of the Integer object?

thanks. that works. i was thinking about that but didn't try, i thought self is object. i am confused about the object and it's value. — meizin

The value of an integer is that same integer. x = 1; x.equal?(x.to_i) is true. In fact, the definition of Integer#to_i is static VALUE int_to_i(VALUE num) { return num; } (equivalent to def to_i; self; end in Ruby). — Amadan

you can just use self as mentioned by messanjah.

Note: if you try object.methods in ruby console for an int like 5.methods, you can find all the methods the object supports like to_i and to_int which also returns the value of the int object so, you can try self.to_int
