', 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.
k Error Messages
The calculator will display an error message when a result exceeds the calculation
range, when you attempt an illegal input, or whenever any other similar problem
occurs.
When an error message appears...
The following are general operations you can use when any error message
appears.
•Pressing d or e displays to the calculation expression editing screen you
were using before the error message appeared, with the cursor located at the
position of the error. For more information, see “Displaying the Location of an
Error”.
•Pressing A clears the calculation expression you input before the error message
appeared. You can then re-input and re-execute the calculation, if you want.
Note that in this case, the original calculation will not be retained in calculation
history memory.
Math ERROR
• Cause
• The intermediate or final result of the calculation you are performing exceeds
the allowable calculation range.
