20 | * ALGORITHM DESCRIPTION: |
21 | * |
22 | * Compute acosh(x) as log(x + sqrt(x*x - 1)) |
23 | * using RSQRT instructions for starting the |
24 | * square root approximation, and small table lookups for log |
25 | * that map to AVX-512 permute instructions |
26 | * |
27 | * Special cases: |
28 | * |
29 | * acosh(NaN) = quiet NaN, and raise invalid exception |
30 | * acosh(-INF) = NaN |
31 | * acosh(+INF) = +INF |
32 | * acosh(x) = NaN if x < 1 |
33 | * acosh(1) = +0 |
