NAME
cacos, cacosf, cacosl - complex arc cosine
SYNOPSIS
#include <complex.h >
double complex cacos(double complex z );
float complex cacosf(float complex z );
long double complex cacosl(long double complex z );
Link with -lm .
DESCRIPTION
The
cacos ()
function calculates the complex arc cosine of
z .
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))
VERSIONS
These functions first appeared in glibc in version 2.1.
CONFORMING TO
C99.
