NAME
atanh(3f) - [FORTRAN:INTRINSIC:MATHEMATICS:TRIGONOMETRIC] Inverse hyperbolic tangent function
SYNTAX
result = atanh(x)
DESCRIPTION
atanh(x) computes the inverse hyperbolic tangent of X.
ARGUMENTS
X The type shall be REAL or COMPLEX.
RETURN VALUE
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-PI/2 <= AIMAG(ATANH(X)) <= PI/2.
EXAMPLE
Sample program:
program demo_atanh implicit none real, dimension(3) :: x = [ -1.0, 0.0, 1.0 ] write (*,*) atanh(x) end program demo_atanh
STANDARD
[[Fortran 2008]] and later
CLASS
