atanh(x) computes the inverse hyperbolic tangent of
Fortran 2008 and later
result = atanh(x)
x- The type shall be
The return value has same type and kind as
x is complex, the imaginary part of the result is in radians and lies between .
program test_atanh real, dimension(3) :: x = (/ -1.0, 0.0, 1.0 /) write (*,*) atanh(x) end program
Inverse function: tanh
