Synopsis

	function atan2(
		x:numeric,
		y:numeric
	)

Arguments

x: An array of one or more values of any dimensionality
y: An array of one or more values with the same dimensionality as x

Description

The atan2 routine returns the arctangent of y/x in the range -pi to pi using the signs of both arguments to determine the quadrant of the return value. The output dimensionality is the same as the input parameters and all missing values are ignored. Return value is of type double if double values are passed in.
