Notes/Examples

Here are some examples of numerical operators in action:

Operator	Supplied Values	Result
Addition	5+5	10
Square root	/81	9
Absolute value	@-8	8
Cube root	/343	7
Factorial	3!	6
Left factorial	!3	6
Binary AND	1&5	1
Binary XOR	1#5	4
Binary left shift	1<<4	16

The binary operators also function on BIT and BITVARYING d ata types. For instance:

Operator	Supplied Values	Result
Binary AND	B'10001'&B'01101'	B'00001'
Binary NOT	~B'01110'	B'10001'
