!, n P r , n C r 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.

π form when using

. 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.
Errors
The calculator will display an error message whenever an error occurs for
any reason during a calculation. There are two ways to exit an error message
display: Pressing
d or e to display the location of the error, or pressing
A to clear the message and calculation.
