I think that I found what you are talking about.

str.to_i(base=10) => integer

Returns the result of interpreting leading characters in str as an 
integer base base (2, 8, 10, or 16). 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.

   "12345".to_i             #=> 12345
   "99 red balloons".to_i   #=> 99
   "0a".to_i                #=> 0
   "0a".to_i(16)            #=> 10
   "hello".to_i             #=> 0
   "1100101".to_i(2)        #=> 101
   "1100101".to_i(8)        #=> 294977
   "1100101".to_i(10)       #=> 1100101
   "1100101".to_i(16)       #=> 17826049

I will have to read this closely.  Thanks!
