csqrt, csqrtf, csqrtl -- complex square root functions SYNOPSIS
#include <complex.h> double complex csqrt(double complex z); float complex csqrtf(float complex z); long double complex csqrtl(long double complex z); DESCRIPTION
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.1-2008 defers to the ISO C standard. These functions shall compute the complex square root of z, with a branch cut along the negative real axis. RETURN VALUE
These functions shall return the complex square root value, in the range of the right half-plane (including the imaginary axis). ERRORS
No errors are defined. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
None. RATIONALE
None. FUTURE DIRECTIONS

cacosh, cacoshf, cacoshl -- complex arc hyperbolic cosine functions SYNOPSIS
#include <complex.h> double complex cacosh(double complex z); float complex cacoshf(float complex z); long double complex cacoshl(long double complex z); DESCRIPTION
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.1-2008 defers to the ISO C standard. These functions shall compute the complex arc hyperbolic cosine of z, with a branch cut at values less than 1 along the real axis. RETURN VALUE
These functions shall return the complex arc hyperbolic cosine value, in the range of a half-strip of non-negative values along the real axis and in the interval [-in, +in] along the imaginary axis. ERRORS
No errors are defined. The following sections are informative. EXAMPLES
