,
√y, x!, nPr, nCr type functions require consecutive internal calculation,
which can cause accumulation of errors that occur with each calculation.
• Error is cumulative and tends to be large in the vicinity of a function's
singular point and inflection point.
• The range for calculation results that can be displayed in π form when
MathI/MathO is selected for Input/Output on the SETTINGS menu is
6
|x| < 10
. Note, however, that internal calculation error can make it
impossible to display some calculation results in π form. It also can
cause calculation results that should be in decimal form to appear in π
form.
