Equals Method (UnitClassProperty)

In This Topic

Is this unit class property equal to the following object?

Syntax

public override bool Equals( 
   object obj
)

Parameters

obj: Object to compare.

Return Value

True if the object is equal to this property, otherwise False.

Remarks

Be careful when comparing unit class properties. The comparison depends on the number of significant digits in project settings. See the code example.

Example

This example shows how the result of comparing unit class properties can be different with different settings.

HpdApi api = HpdApi.GetInstance();
					
// Prepare almost the same values.
LengthProperty length1 = new LengthProperty(1.000000001, Unit.Millimeter);
LengthProperty length2 = new LengthProperty(1, Unit.Millimeter);
					
// Set significant figures for all units to 3.
api.CurrentProject.Settings.Units.SignificantFigures = 3;

Console.WriteLine($"Is '{length1}' equal to '{length2}'? {length1 == length2}.");
					
// Extend the significant figures for all units to 10.
api.CurrentProject.Settings.Units.SignificantFigures = 10;

Console.WriteLine($"Is '{length1}' equal to '{length2}'? {length1 == length2}.");
					
// RESULTS:
// Is '1 mm' equal to '1 mm'? True.
// Is '1,000000001 mm' equal to '1 mm'? False.
