Truncation errors occur when a primitive is cast to a primitive
					of a smaller size and data is lost in the conversion.When a primitive is cast to a smaller primitive, the high order bits of
						the large value are lost in the conversion, potentially resulting in an
						unexpected value that is not equal to the original value. This value may be
						required as an index into a buffer, a loop iterator, or simply necessary
						state data. In any case, the value cannot be trusted and the system will be
						in an undefined state. While this method may be employed viably to isolate
						the low bits of a value, this usage is rare, and truncation usually implies
						that an implementation error has occurred.
