where {Dn} is the dynamic k factor acting as follows:

-64 to 0   - indicates the number of significant digits to the right of the
            decimal point
+1 to +17  - indicates the number of significant digits in the mantissa
+18 to +63 - Sets the OPERR bit in the FPSR exception byte, treated as +17
