How do you do (explicit) type conversion in ruby? I just want to make
/“2” + “3” = 5/ , but it, of course, gives me /“23”/ and not /5/.

a = [74, 117, 115, 116, 32, 65, 110, 111, 116, 104, 101, 114, 32, 82]
a.push(117,98, 121, 32, 72, 97, 99, 107, 101, 114)
puts a.pack(“C*”)
irb(main):001:0> ‘2’.to_i + ‘3’.to_i
5
each class has (does not have) it’s own conversion methods. so, for instance,
check the docs for String to see how to convert to a number.
