------------------------------------------------------------ String#to_i
     str.to_i(base=10)   => integer
------------------------------------------------------------------------
     Returns the result of interpreting ***leading characters*** in 
_str_ as
     an integer... .Extraneous characters
     past the end of a valid number are ****ignored***.

     If there is not a valid
     number at the start of _str_, +0+ is returned. This method never
     raises an exception.


----------------------------------------------------------- String#chomp
     str.chomp(separator=$/)   => new_str
------------------------------------------------------------------------
     Returns a new +String+ with the given record separator removed from
     the end of _str_ (if present)....

        "hello".chomp            #=> "hello"
        "hello\n".chomp          #=> "hello"
        "hello\r\n".chomp        #=> "hello"
        "hello\n\r".chomp        #=> "hello\n"
        "hello\r".chomp          #=> "hello"
        "hello \n there".chomp   #=> "hello \n there"
        "hello".chomp("llo")     #=> "he"




Based on those descriptions will the result returned by

input.chomp().to_i

be any different than the result returned by:

input.to_i

??
