ASINH — Inverse hyperbolic sine function#

ASINH(X)#

ASINH(X) computes the inverse hyperbolic sine of X.

Parameters

X – The type shall be REAL or COMPLEX.

Returns

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.

Standard:

Fortran 2008 and later

Class:

Elemental function

Syntax:
RESULT = ASINH(X)
Example:
PROGRAM test_asinh
  REAL(8), DIMENSION(3) :: x = (/ -1.0, 0.0, 1.0 /)
  WRITE (*,*) ASINH(x)
END PROGRAM
