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 $-\pi/2 \leq \mathop{Im}{\asinh(x)} \leq \pi/2$.

Example

program test_asinh
  real(8), dimension(3) :: x = (/ -1.0, 0.0, 1.0 /)
  write (*,*) asinh(x)
end program
