Operator Precedence

For expressions with three or more operands (i.e. 2 - 244 / 4), rules of precedence apply. The order of precedence for operators is listed from highest to lowest:

Operator Type	Operator
Unary Operators	@, Not
Multiplying Operators	, /, Div, Mod, And, Shl, Shr*
Adding Operators	+, -, Or, Xor
Relational Operators	=, <>, <, >, <=, >=, In

Operations are performed from left to right while operations of higher precedence are performed first. For instance, the following expression:

  7 + 4 * 2

is not the same as:

  (7 + 4) * 2

Since multiplication has a higher precedence than addition, multiplication is performed first followed by addition. Use parenthesis to separate operations that you want to be performed first.
