SYNTAX
x = tanh(x)
DESCRIPTION
tanh(x) computes the 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. If X is REAL, the return value lies in the range
-1 <= tanh(x) <= 1.
EXAMPLE
Sample program:
program demo_tanh real(8) :: x = 2.1_8 x = tanh(x) end program demo_tanh
STANDARD
[[FORTRAN 77]] and later, for a complex argument [[Fortran 2008]] or later
