+//                     ALGORITHM DESCRIPTION
+//                     ---------------------
+//
+//    Let x=2^k * mx, mx in [1,2)
+//
+//    Get B~1/mx based on the output of rcpss instruction (B0)
+//    B = int((B0*LH*2^7+0.5))/2^7
+//    LH is a short approximation for log10(e)
+//
+//    Reduced argument: r=B*mx-LH (computed accurately in high and low parts)
+//
+//    Result:  k*log10(2) - log(B) + p(r)
+//             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:
+//  log10(0) = -INF with divide-by-zero exception raised                                           
+//  log10(1) = +0
+//  log10(x) = NaN with invalid exception raised if x < -0, including -INF
+//  log10(+INF) = +INF
+//
