| // ALGORITHM DESCRIPTION - LOG() |
| // --------------------- |
| // |
| // x=2^k * mx, mx in [1,2) |
| // |
| // Get B~1/mx based on the output of rcpss 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) if |x-1| >= small value (2^-6) and |
| // 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: |
| // log(NaN) = quiet NaN, and raise invalid exception |
| // log(+INF) = that INF |
| // log(0) = -INF with divide-by-zero exception raised |
| // log(1) = +0 |
| // log(x) = NaN with invalid exception raised if x < -0, including -INF |
