CALCULATION ERRORS
E (error) appears at the upper left of the
display when:
• A calculation result exceeds 10 dig-
its (this is an overflow error see

ESTIMATING
CALCULATION RESULTS
If you perform an operation that results
in an overflow error, you can estimate
the approximate value (to 10 significant
digits) by following this procedure.
1. Count the number of digits dis-
played to the left of the decimal
point.
2. Remove the decimal point.
