Subject: converting chars to numeric


Hi.

I am new to ruby and coming from a Perl environment.

Can someone tell me if there is a nice way to do the following:

         s = "4567"
         a = s[0]                # --> I want the value '4' not '54', the 
ASCII value of 4
         b = s[1]                # --> 5
         a + b                   # --> 9

I can do this by saying

         a = s[0] - 48

though this seems a might ugly for ruby :-).

TIA,




-mark.
