Convert a string to a number

Hey Gang,

  I have a script that is manipulating a list of IP addresses.  I am
trying to get the last octet and determine what the next one would be.
I can get my list into an array.  I can trim off what I don't want (the
xx.xx.xx. piece) but the remaining piece is a string.  I tried using
Number but it returns zero.  So how can I convert it back into a number?

 

Thanks!
