General description
Calculates the hyperbolic tangent of x, where x is expressed in radians.
Returned value
Returns the calculated value of the hyperbolic tangent of x.
If the result underflows, the function returns 0 and sets the errno to ERANGE.
Example
CELEBT23
/* CELEBT23
This example illustrates the tanhd64() function.
This example computes x as the hyperbolic tangent of PI/4.
