Is it ever necessary to use 'chomp' before using `to_i` or `to_f`?
ruby
Solution
There is no need to use `chomp` method because:
`String#chomp` returns a new String with the given record separator removed from the end of str (if present). If `$/` has not been changed from the default Ruby record separator, then `chomp` also removes carriage return characters (that is it will remove "\n", "\r", and "\r\n"). Here are some examples.
`String#to_f` returns the result of interpreting leading characters in `str` as a floating point number. Extraneous characters past the end of a valid number are ignored. If there is not a valid number at the start of `str`, 0.0 is returned. This method never raises an exception. Here are some examples for `to_f`.
Problem
I see people use the following code: ``` gets.chomp.to_i ``` or ``` gets.chomp.to_f ``` I don't understand why, when the result of those lines are always the same as when there is no `chomp` after `gets`. Is `gets.chomp.to_i` really necessary, or is `gets.to_i` just enough?
