If you perform a calculation that results in an
overflow error, you can estimate the correct
result (to eight significant digits) by following
these steps.
1. Count the number digits displayed to
the left of the decimal point.
2. Remove the decimal point.
3. Add as many zeros to the right of the
number as there were digits to the left
of the decimal point.
For example, if the display shows
;;;;
'$&'*(&,* '$&'*(&,* '$&'*(&,* '$&'*(&,*
, the approximate answer is
101,420,640.
