•Precision is basically the same as that described under “Calculation Range and Precision”, above.

•^(xy), x'y, 3', 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.

kError 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 Aclears 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.
