Examples of these special functions are shown here using both the ALG and

RPN modes. As an exercise, verify that GAMMA(2.3) = 1.166711…,

PSI(1.5,3) = 1.40909.., and Psi(1.5) = 3.64899739..E-2.

These calculations are shown in the following screen shot:

To have access to these constants, select option 11. CONSTANTS.. in the

The constants are listed as follows:

Selecting any of these entries will place the value selected, whether a symbol

(e.g., e, i, π, MINR, or MAXR) or a value (2.71.., (0,1), 3.14.., 1E-499,

9.99..E499) in the stack.
