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.
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
or displays to the calculation expression
editing screen you were using before the error message
appeared, with the cursor located at the position of error.
For more information see “Displaying the Location of an
Error.”
• Pressing
clears the calculation expression you were
using 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 calculations range.
• Your input exceeds the allowable input range (particularly
when using functions).
• The calculation you are performing contains an illegal
mathematical operation (such as division by zero).
