A Tiny (WP34S) program does a lot

The derivative of the gamma function is the digamma function (ψ), well is trivial to get the derivative from this. This function was implemented both in C and in XROM but it was omitted from the final firmware. It remains a compile time option.

Oh, SLV is a condition, it skips a step if it can't find a solution. Better would be two RTN statements after the SLV not one.
