double cacos(double complex z);
float cacosf(float complex z);
long double cacosl(long double complex z);
The functions compute a complex arc cosine value.
z - a complex number.
These functions compute the complex arc cosine of z, with branch cuts outside the interval [-
1] along the real axis.
These functions return the complex arc cosine of z, in the range of a strip mathematically unbounded along the imaginary axis and in the interval [0,π] along the real axis.
No errors are defined.
