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

Ruby

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

irb> “1.5”.to_f
=> 1.5

But if I do:

irb> “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.

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)
