Estimating Calculation Results

If you perform a calculation that results in an overflow error, you
can estimate the correct result (to 10 significant digits) by fol-

1. Count the number of digits displayed to the left of the deci-

3. Add as many zeros to the right of the number as there were
digits to the left of the decimal point.

E 251.0142064
answer is 2,510,142,064,000. If
the approximate answer is 173,197,034,700,000.
