Computes the hyperbolic tangent of numeric types.

Prototype

	function tanh (
		value  : numeric   
	)

	return_val [dimsizes(value)] :  float or double

Arguments

One or more floating-point values of any dimension, in radians.

Return value

Returns an array dimensioned the same as value.

The return type is floating point if the input is floating point, and double if the input is of type double.

Description

This function returns the hyperbolic tangent of each element of value. Missing values are ignored.
