pb4072, @EVAL lets you do some pretty advanced math as well. It supports exponentiation, bit-manipulation operations, logarithms, trigonometric functions, etc., etc. Want to know what pi is out to 15,000 decimal places? It's got that covered. It's really quite a powerful function should you ever need any of those facilities.
If I have any (very minor) gripe about it, it's that it has no particularly straightforward way to compute roots but I figured out how to get it to do those, too. You can do that by raising a number to the power of the reciprocal of the root you're trying to find. E.g., to find the cube root of n, use @EVAL[n**(1/3)].
