This is driving me slightly nuts. I want to do some very simple arithmetic,
but always make sure I return a positive number, even if the result of the
calculation is a negative.

Basically convert -4 to 4, etc.

So I've been trawling the manual for functions and Googling, and can't find
a thing. Lots of stuff about formatting string with sprintf, and stuff about
converting float to ints, but nothing as obvious as this.

Suggestions gratefully received.
