32// ALGORITHM DESCRIPTION
33// ---------------------
34//
35// Let x=2^k * mx, mx in [1,2)
36//
37// Get B~1/mx based on the output of rcpps instruction (B0)
38// B = int((B0*2^7+0.5))/2^7
39//
40// Reduced argument: r=B*mx-1.0 (computed accurately in high and low parts)
41//
42// Result: k*log(2) - log(B) + p(r)
43// p(r) is a degree 7 polynomial
44// -log(B) read from data table (high, low parts)
45// Result is formed from high and low parts
46//
47// Special cases:
48// log1p(NaN) = quiet NaN, and raise invalid exception
49// log1p(+INF) = that INF
50// log1p(x) = NaN if x < -1 or x = -INF, and raises invalid exception
51// log1p(-1) = -INF, and raises divide-by-zero exception
52// log1p(+/-0) = +/-0
53//
