Search for "Numerical Recipes" by Press et al. There is an online
version somewhere, but I didn't keep it because I have the book ;-)
I think Sinan mentioned it a few weeks ago, so you can check the
mail archives on www.delorie.com.
They also have a version of all programms on diskette, I'd recommend
that, too. Compiles fine, except for some minor flaws, like
naming a routine "select". 
Otherwise it has loads of interesting numerical algorithms for
everyday use.
