Estimating Calculation Results
If you perform an operation that results in an overflow error, you
can estimate the correct result (to 12 significant digits) by fol-
lowing these steps.
1. Count the number of digits displayed to the left of the deci-
mal point.
2. Remove the decimal point.
3. Add as many zeros to the right of the number there were
digits to the left of the decimal point.
For example, if
E
1.23456789012
appears, the estimated
answer is 1,234,567,890,120.
