Nice!

Any pointers on where to find out more about how to use idiv, mod, 
etc.?  I'd like to get a better sense of the basics: the logic that 
explains how the above works (e.g. what's going on with the "div 100" 
that gives me the last two digits, what does mod do, etc.). The xpath 
2.0 spec isn't all that helpful for me.
