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 imaginary axis and in the interval [ 0, ?? ] along the real axis.

Errors

No errors are defined.
