ccos, ccosf, ccosl - complex cosine functions
double complex ccos(double complex z);
float complex ccosf(float complex z);
long double complex ccosl(long double complex z);
[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1-2017 defers to the ISO C standard.
These functions shall compute the complex cosine of z.
These functions shall return the complex cosine value.
