ACOSH(3f)

DESCRIPTION
ACOSH(X) computes the inverse hyperbolic cosine of X.

STANDARD
Fortran 2008 and later

CLASS
Elemental function

SYNTAX
RESULT = ACOSH(X)

ARGUMENTS

X The type shall be REAL or COMPLEX.

RETURN VALUE
The return value has the same type and kind as X. If X is complex, the imaginary part of the result is in radians and lies between
 0 <=q Im acosh(x) <=q PI.

EXAMPLE
          PROGRAM test_acosh
            REAL(8), DIMENSION(3) :: x = (/ 1.0, 2.0, 3.0 /)
            WRITE (*,*) ACOSH(x)
          END PROGRAM
