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.

Return value

These functions return the complex arc hyperbolic cosine of z, in the range of a half-strip [0,&#x03C0] of non-negative values along the real axis and in the interval [-iπ, +iπ] along the imaginary axis.
