9.8 ACOSH — Inverse hyperbolic cosine function
- 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
orCOMPLEX
. - 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 \leq \Im \acosh(x) \leq \pi.
- Example:
-
PROGRAM test_acosh REAL(8), DIMENSION(3) :: x = (/ 1.0, 2.0, 3.0 /) WRITE (*,*) ACOSH(x) END PROGRAM
- Specific names:
-
Name Argument Return type Standard DACOSH(X)
