Math functions? (Particularly transcendental ones)

[Dan Sugalski]

Okay, I'm whipping together the "fancy math" section of the interpreter 
assembly language. I've got:

sin, cos, tan           : Plain ones
asin, acos, atan        : arc-whatevers
shinh, cosh, tanh       : Hyperbolic whatevers
log2, log10, log        : Base 2, base 10, and explicit base logarithms
pow                     : Raise x to the y power

Can anyone think of things I've forgotten? It's been a while since I've 
done numeric work.
