58 * ALGORITHM DESCRIPTION - LOG()
59 * ---------------------
60 *
61 * x=2^k * mx, mx in [1,2)
62 *
63 * Get B~1/mx based on the output of rcpss instruction (B0)
64 * B = int((B0*2^7+0.5))/2^7
65 *
66 * Reduced argument: r=B*mx-1.0 (computed accurately in high and low parts)
67 *
68 * Result: k*log(2) - log(B) + p(r) if |x-1| >= small value (2^-6) and
69 * p(r) is a degree 7 polynomial
70 * -log(B) read from data table (high, low parts)
71 * Result is formed from high and low parts.
72 *
73 * Special cases:
74 * log(NaN) = quiet NaN, and raise invalid exception
75 * log(+INF) = that INF
76 * log(0) = -INF with divide-by-zero exception raised
77 * log(1) = +0
78 * log(x) = NaN with invalid exception raised if x < -0, including -INF
