!, 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.

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

B or C to display the location of the error, or pressing

to clear the message and calculation.

Displaying the Location of an Error

While an error message is displayed, press

B or C to return to the

calculation screen. The cursor will be positioned at the location where
the error occurred, ready for input. Make the necessary corrections to the
calculation and execute it again.
