true if obj is an instance of Double and equals the value of this instance; otherwise, false.

The precision of floating-point numbers beyond the documented precision is specific to the implementation and version of the .NET Framework. Consequently, a comparison of two particular numbers might change between versions of the .NET Framework because the precision of the numbers' internal representation might change.

The following code example demonstrates the Equals method.

obj1 = (Double)500;
if (a.Equals(obj1)) {
    Console.WriteLine("The value type and reference type values are equal.");
}

obj1 = new Double(500);
if (obj1.Equals(a)) {
    Console.WriteLine(
        "The value type and reference type values are equal.");
