"double complex cacos(double complex "z);

"float complex cacosf(float complex "z);

"long double complex cacosl(long double complex "z);

DESCRIPTION

The cacos() function calculates the complex acos(). If y = cacos(z), then z = ccos(y). The real part of y is chosen in the interval [0,pi].

One has cacos(z) = -i clog(z+csqrt(z*z-1)).
