Constructor & Destructor Documentation

◆ __construct()

assNumericRange::__construct	(	$lowerlimit = `0.0`,
		$upperlimit = `0.0`,
		$points = `0.0`,
		$order = `0`
	)

assNumericRange constructor

The constructor takes possible arguments an creates an instance of the assNumericRange object.

Parameters

double	$lowerlimit	The lower limit of the range
double	$upperlimit	The upper limit of the range
double	$points	The number of points given for the correct range
integer	$order	A nonnegative value representing a possible display or sort order
