| Functions and CALL Routines |
Returns the hyperbolic tangent.
|
CALL TANH(argument<, argument,...>);
|
-
argument
-
is numeric.
| Restriction: |
The CALL TANH routine
only accepts variables as valid arguments. Do not use a constant or a SAS
expression, because the CALL routine is unable to update these arguments. |
The subroutine TANH replaces each argument
by the tanh of that argument. For example
![[equation]](images/leqn26.gif)
is replaced by
![[equation]](images/deqn28.gif)
If any argument contains a missing value, then CALL TANH returns missing
values for all the arguments.
The following SAS statements produce these
results:
