Operators and precedence

Unary operator expressions:

<operator> <operand>

Binary operator expressions:

<operand1> <operator> <operand2>

Arithmetic operators

Operator	Function	Example	Description
\*	Multiplication	a * b	Multiply the two operands.
/	Division	a / b	Divide the first operand by the second operand.
+	Addition	a + b	Add the two operands.
-	Subtraction	a - b	Subract the second operand from the first operand.
-	Unary minus, negation	-a	Negates the operand

Operator	Function	Example	Description
not	Logical negation	not a	Negates the boolean operand.
and	Logical AND	a and b	Performs a logical-AND of two bool operands. The second operand is only evaluated if necessary, which is when the first operand is true.
or	Logical OR	a or b	Performs a logical-OR of the two bool operands. The second operand is only evaluated if necessary, which is when the first operand is false.

Operator	Function	Example	Description
<	Less than	a < b	Returns true if the first operand is less than the second operand.
>	Greater than	a > b	Returns true if the first operand is greater than the second operand.
<=	Less than or equal to	a <= b	Returns true if the first operand is less than or equal to the second operand.
>=	Greater than or equal to	a >= b	Returns true if the first operand is greater than or equal to the second operand.

Operator	Function	Example	Description
=	Equal to	a = b	Returns true if the two operands are equal.
<>	Not equal to	a <> b	Returns true if the two operands are not equal.

Operator	Function	Example	Description
??	Null coalescing operator	a ?? b	Returns the first operand if it is not null, otherwise it returns the second operand.
!??	Not null coalescing operator	a !?? b	Returns the second operand if the first operand is not null, otherwise it returns null.

The operators are grouped in order of precedence. Operators within the same group have the same precedence.
