Functions								Input Range
	x > 0: –1×10100< ylog x < 100
^( y)	x = 0: y > 0	m
x	x < 0: y = n, 2n+1 (m, n are integers)
	However: –1×10100<				y	log	x	< 100
	y > 0: x G 0, –1×10100< 1/x logy < 100
x'	y = 0: x > 0		2n+1
y	y < 0: x = 2n+1,			m		(m G 0; m, n are integers)
	However: –1×10100< 1/xlog y < 100
a b/c	Total of integer, numerator, and denominator must be 10 digits or less (including
	separtor symbols).

•^(xy), x'y , 3', x!, nPr, nCr type functions require consecutive internal calculation, which can result in accumulation of errors that occur within each individual calculation.

•Errors are cumulative and tend to be large in the vicinity of a function’s singular point and inflection point.

k Error Messages

An error message will appear on the screen if you perform a calculation that causes a calculator’s limit to be exceeded, or if you try to perform some operation that is not allowed.

Sample Error Message

A Recovering from an Error Message

You can recover from an error message by performing the key operations described below, regardless of the error type.

•Press J, d or e to display the editing screen for the calculation expression you input immediately before the error occurred, with the cursor positioned at the location that caused the error. For more information, see “Finding the Location of an Error” on page 21.

•Pressing o clears the calculation expression you input before the error message appeared. Note that in this case, the original calculation will not be retained in calculation history memory.

A Error Message Reference

This section lists all of the error messages that the calculator displays, as well as their causes and what you need to do to avoid them.
