- inverse hyperbolic cosine functions
c99 [ flag... ] file... -lm [ library... ] #include <math.h> double acosh(double x);
float acoshf(float x);
long double acoshl(long double x);
These functions compute the inverse hyperbolic cosine of their argument x.
Upon successful completion, these functions return the inverse hyperbolic cosine of their argument.
For finite values of x < 1, a domain error occurs and NaN is returned.
If x is NaN, NaN is returned.
If x is +1, +0 is returned.
If x is +Inf, +Inf is returned.
If x is -Inf, a domain error occurs and NaN is returned.
For exceptional cases, matherr(3M) tabulates the values to be returned by acosh() as specified by SVID3 and XPG3.
These functions will fail if:
The x argument is finite and less than 1.0, or is -Inf.
If the integer expression (math_errhandling & MATH_ERREXCEPT) is non-zero, the invalid floating-point exception is raised.
The acosh() function sets errno to EDOM if x is less than 1.0.
An application wanting to check for exceptions should call feclearexcept(FE_ALL_EXCEPT) before calling these functions. On return, if fetestexcept(FE_INVALID | FE_DIVBYZERO | FE_OVERFLOW | FE_UNDERFLOW) is non-zero, an exception has been raised. An application should either examine the return value or check the floating point exception flags to detect exceptions.
An application can also set errno to 0 before calling acosh(). On return, if errno is non-zero, an error has occurred. The acoshf() and acoshl() functions do not set errno.
