H A Dcatrig.c69 * The functions casin(h) and cacos(h) are about 2.5 times slower than asinh.
72 * The code for casinh, casin, cacos, and cacosh comes first. The code is
82 * | casinh, casin, cacos, cacosh |
148 * rx = Re(casinh(z)) = -Im(cacos(y + I*x)).
214 * later on. For cacos this would not be legitimate.
346 * cacos(z) = PI/2 - casin(z)
347 * but do the computation carefully so cacos(z) is accurate when z is
350 * cacos(z) = PI/2 - z + O(z^3) as z -> 0
