Is posible String#to_s doesn't add the decimal value if not needed?

Hi, I want to convert a string to a Float value:

  > "1.5".to_f
  => 1.5

But if I do:

  > "1".to_f
  => 1.0

I get '1.0' instead of just '1'. Is not possible to just get '1' in this case?

Thanks a lot.

n = Integer(n) rescue Float(n)

Well, you could do this:

a = ["1", "1.5"].map do |x|
   Float x # validate
   eval x
end

p a

Just a thought....

Numeric("1.5").should_return(1.5)
Numeric("1").should_return(1)
