Operator precedence

Home » Help Extras » Helpful Tips » Operator precedence

Each operator has an order of precedence. Use the chart below as a guide. HyperCard evaluates operators with lower order numbers before those with higher order numbers. Operators with the same order number are evaluated in an expression from left to right.

Order   Operators

1      ()

2      - [minus sign]

not

       there is a

       there is an

       there is not a

       there is not an

       there is no

3      ^

4      * / div mod

5      + -

6      & &&

7      < > <= >= ≤ ≥

       is in

       contains

       is not in

       is a

       is an

       is not a

       is not an

       is within

       is not within

8      = is

       is not <> ≠

9      and

10      or

Use parentheses to eliminate ambiguity in the process of evaluation—parentheses have the highest order of precedence: (3+2) * 5 = 25. If you use parentheses, HyperCard evaluates the innermost parenthetical expression first.
