 				Converts a [Variant] var to JSON text and returns the result. Useful for serializing data to store or send over the network.
 				[b]Note:[/b] The JSON specification does not define integer or float types, but only a [i]number[/i] type. Therefore, converting a Variant to JSON text will convert all numerical values to [float] types.
