9.19 ASINH — Inverse hyperbolic sine function
- Description:
-
ASINH(X)
computes the inverse hyperbolic sine of X. - Standard:
- Fortran 2008 and later
- Class:
- Elemental function
- Syntax:
-
RESULT = ASINH(X)
- Arguments:
-
X The type shall be REAL
orCOMPLEX
. - Return value:
- The return value is of the same type and kind as X. If X is complex, the imaginary part of the result is in radians and lies between -\pi/2 \leq \Im \asinh(x) \leq \pi/2.
- Example:
-
PROGRAM test_asinh REAL(8), DIMENSION(3) :: x = (/ -1.0, 0.0, 1.0 /) WRITE (*,*) ASINH(x) END PROGRAM
