ASINH — Inverse hyperbolic sine function

Description

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

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
