Reusing a constant I already had rather than introducing a new one.

Quote:But there seems to be another problem with the regularized Gamma functions Γp and Γq for large arguments. Try e.g. 1E12 ENTER Γp or Γq. This should yield roughly 0,5 while it actually returns –22,6673 (!) resp. 1 – this = 23,6673.

I'm about ready to give on on these functions and the incomplete beta
