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:
Calculator constants
The following are the mathematical constants used by your calculator:
• e: the base of natural logarithms.
• i: the imaginary unit, i
i 2
= -1.
• π: the ratio of the length of the circle to its diameter.
• MINR: the minimum real number available to the calculator.
• MAXR: the maximum real number available to the calculator.
To have access to these constants, select option 11. CONSTANTS.. in the
MTH menu,
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.
