//                     ALGORITHM DESCRIPTION - LOG10()

//                     ---------------------

//

//    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

//
