+//                     ALGORITHM DESCRIPTION
+//                     ---------------------
+//
+//    x=2^k * mx, mx in [1,2)
+//
+//    Get B~1/mx based on the output of rcpss instruction (B0)
+//    B = int((B0*2^7+0.5))/2^7
+//
+//    Reduced argument: r=B*mx-1.0 (computed accurately in high and low parts)
+//
+//    Result:  k*log(2) - log(B) + p(r) if |x-1| >= small value (2^-6)  and
+//             p(r) is a degree 7 polynomial
+//             -log(B) read from data table (high, low parts)
+//             Result is formed from high and low parts
+//
+// Special cases:
+//  log(NaN) = quiet NaN, and raise invalid exception
+//  log(+INF) = that INF
+//  log(0) = -INF with divide-by-zero exception raised
+//  log(1) = +0
+//  log(x) = NaN with invalid exception raised if x < -0, including -INF
+//
