*
* 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
*
