Mathematical Library Functions                          cacos(3M)



NAME
     cacos, cacosf, cacosl - complex arc cosine functions

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include 

     double complex cacos(double complex z);


     float complex cacosf(float complex z);


     long double complex cacosl(long double complex z);


DESCRIPTION
     These functions compute the complex arc cosine  of  z,  with
     branch  cuts  outside the interval [ -1, +1 ] along the real
     axis.

RETURN VALUES
     These functions return the complex arc cosine value, in  the
     range  of  a  strip  mathematically unbounded along the ima-
     ginary axis and in the interval  [ 0, pi ]  along  the  real
     axis.

ERRORS
     No errors are defined.
