This was never intended to be used by anyone but me, but the snippets page dared me :)
Actually, in a bot called cu2q, I've got this really nice !calc function, but I still need to get it out of there and into a separate script. It's hundreds of lines, and based on this lil' snippet.

17:10 <Juerdje> !calc one thousand times the square root of
                threehundredandsixtytwo
17:10 <cu2q> 1000*sqrt 362 = 19026.2975904404
17:10 <Juerdje> !calc ~0
17:10 <cu2q> ~0 = 4294967295
17:10 <Juerdje> !calc -o:eng ~0
17:10 <cu2q> ~0 =

When I'm done, I'll try to have it strict and with warnings. And when that's done (somewhere next year), I'll put it on perlmonks :)
