93 pExponent = pointer to the integer part of Log2 of type Word16 whose
95 pFraction = pointer to the fractional part of Log2 of type Word16
101 pExponent -> integer part of the newly calculated Log2
102 pFraction -> fractional part of the newly calculated Log2
103 pOverflow -> 1 if the log2() operation resulted in saturation
