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 or COMPLEX.
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
Specific names:
Name Argument Return type Standard
DASINH(X) REAL(8) X REAL(8) GNU extension.
