//                     ALGORITHM DESCRIPTION
//                     ---------------------
//
//    Let x=2^k * mx, mx in [1,2)
//
//    Get B~1/mx based on the output of rcpps 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)
//             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:
//   log1p(NaN) = quiet NaN, and raise invalid exception
//   log1p(+INF) = that INF
//   log1p(x) = NaN if x < -1 or x = -INF, and raises invalid exception
//   log1p(-1) = -INF, and raises divide-by-zero exception
//   log1p(+/-0) = +/-0
//
