atanh(x)
computes the inverse hyperbolic tangent of x
.
Fortran 2008 and later
result = atanh(x)
x
- The type shall be real
or complex
.The return value has same type and kind as x
. If 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
