Golliver's Technique (cont'd)

Scaling
Prevents the double rounding.
A technique that causes underflows properly on FPU registers.

Scaling down
Multiplies one of the operands by a scale.
Scaling up
Multiplies the result by the reciprocal number of the scale.
             (or divides the result by the scale.)

Scale
For double-precision operation:  2 ** -16382-(-1022)
For single-precision operation:    2 ** -16382-(-126)

Multiplication and division need this technique.
Double rounding can only occur for mult. and div.
