cosh

Computes the hyperbolic cosine of numeric types.

Prototype

	function cosh (
		value  : numeric   
	)

	return_val [dimsizes(value)] :  float or double

Arguments

value

One or more 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 cosine of each element of value. Missing values are ignored.
