Hierarchy of Operators
Expressions in the Assemblers are evaluated using the following precedence rules:
• Parentheses form the primary level of hierarchy and force precedence - their
contents are performed first;
• Without the aid of parentheses, operators are performed in the order dictated by
the hierarchy table;
• Operators with similar precedence are performed in the direction of their
associativity - normally, from left to right, except unary operators.
