Estimating Calculation Results

If you perform a calculation that results in an overflow error, you can estimate the cor- rect result (to 8 significant digits) by follow- ing these steps.

1.Count the number of 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, the displayed value ERROR 1.0142064 is estimated to equal 101,420,640.
