How about for math:
 * ceil (round up)
 * trunc (round toward 0)
 * min
 * max
 * lcm (Least Common Multiple)
 * gcd (Greatest Common Divisor)
 * nCr (http://en.wikipedia.org/wiki/Combination)
 * nPr (http://en.wikipedia.org/wiki/Permutation)
 * fac (x!: http://en.wikipedia.org/wiki/Factorial)
 * Reciprocal and hyperbolic trig functions (csc, sec, cot, sinh, etc.)
