√ , 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 setup menu is |

.
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.
