Digamma Function for the free42

[Juan14]

Thanks Albert, the new improvement loos neat, I didn’t even consider complex numbers, I used the register 11 just in case someone wanted to try it in the hp 42s, I was using a local variable (LSTO “x”) in my free42 and also FUNC 11 at the start of the program so the program behaves like a build in function..
I always thought the hp 50g should have a list that acts like the registers in the RPN calculators with the arithmetic functions, that implementation in the free42 would be awesome.
