double cacosh(double complex z);
float cacoshf(float complex z);
long double cacoshl(long double complex z);
The functions compute a complex arc hyperbolic cosine value.
z - a complex number.
These functions compute the complex arc hyperbolic cosine of z, with branch cut at values less than
1 along the real axis.
These functions return the complex arc hyperbolic cosine of z, in the range of a half-strip [0,π] of non-negative values along the real axis and in the interval [-iπ, +iπ] along the imaginary axis.
No errors are defined.
