casting a primitive type
subject			fact

casting a primitive type	cannot be used to convert a primitive type to an object
	has example //i is an int //d is a double (double) i // a double expression (int) d // an int expression // note that the original types of i and d remain the same
	has syntax (typename)value
	is a subtopic of Objects
	is a kind of casting
	may be done implicitly if the destination type is larger than the source type (such as using a byte as an int)
	may not involve a Boolean type
	must be done explicitly if the destination type is smaller than the source type to avoid loss of precision
casting	has purpose to convert an instance of one data type into another which is a subclass of the original type
