• In the function
variables (A through Z, r, & ) are treated as constants, and the value currently
assigned to that variable is applied during the calculation.

• Discontinuous points or sections with drastic fluctuation can adversely affect
precision or even cause an error.
• Note that you cannot use a Solve, differential, quadratic differential, integration,
maximum/minimum value or ! calculation expression inside of a maximum/
minimum calculation term.
• Inputting a larger value for
