TANH Function

Description

The TANH function returns the hyperbolic tangent of a REAL argument.

Syntax
 
TANH (x)
 

Arguments

x is an INTENT(IN) scalar or array of type REAL.

Result

The result is of the same type and kind as x. Its value is a REAL representation of the hyperbolic tangent of x.

Example
       real :: x..5,y(2)=(/1.,1./)
       write(*,*) tanh(x) ! writes .4621171
       write(*,*) tanh(y) ! writes .7615941 .7615941
