public static FilterRule CreateLessRule(
	ElementId parameter,
	double value,
	double epsilon
)

	double epsilon
)

Parameters

parameter
Type: Autodesk.Revit.DB..::..ElementId
A double-typed parameter used to get values from the document for a given element.
value
Type: System..::..Double
The user-supplied value against which values from the document will be compared.
epsilon
Type: System..::..Double
Defines the tolerance within which two values may be considered equal.

Remarks

Values less than the user-supplied value but within epsilon are considered equal, not less.

Exceptions

ExceptionCondition
Autodesk.Revit.Exceptions..::..ArgumentException The given value for value is not finite -or- The given value for value is not a number -or- The given value for epsilon is not finite -or- The given value for epsilon is not a number
