[bjbfubbm] Real factorial

If a scientific calculator already has a factorial function, then it would be easy to extend it to all real values, providing the value of gamma(n+1), the capital Pi function of Riemann.

Similarly, the binomial coefficient function, nCr, can be extended to all real numbers via the Beta function, offset and scaled.

These can be further extended to complex inputs and outputs, if the calculator does complex numbers.
