+     where Rcp ~ 1/x (accuracy ~9 bits, obtained by rounding
+     HW approximation to 1+9 mantissa bits)

+   Reduced argument R=Rcp*x-1 is used to approximate log(1+R) as polynomial
+
+   log(Rcp) = exponent_Rcp*log(2) + log(mantissa_Rcp)
+     -log(mantissa_Rcp) is obtained from a lookup table,
