Precedence of assembler operators
Each operator has a precedence number assigned to it that determines the order in which the operator and its operands are evaluated. The precedence numbers range from 1 (the highest precedence, that is, first evaluated) to 15 (the lowest precedence, that is, last evaluated).
These rules determine how expressions are evaluated:
The highest precedence operators are evaluated first, then the second highest precedence operators, and so on until the lowest precedence operators are evaluated.
Operators of equal precedence are evaluated from left to right in the expression.
Parentheses ( and ) can be used for grouping operators and operands, and for controlling the order in which the expressions are evaluated. For example, this expression evaluates to 1:
7/(1+(2*3))
Note
The precedence order in the IAR Assembler for RL78 closely follows the precedence order of the ANSI C++ standard for operators, where applicable.
