Hello,
It *is* documented in AFL Reference manual (press F1).
http://www.amibroker.com/guide/a_language.html
Operator precedence and the parentheses
AFL supports parentheses in formulas.
Parentheses can be used to control the operation precedence (the order in which the operators are calculated). AmiBroker always does operations within the innermost parentheses first. When parentheses are not used, the precedence is as follows (higher precedence listed first):
No Symbol Meaning
1 ++ Post-increment/pre-increment
(i++ works like i = i + 1)
2 -- Post-decrement/pre-decrement
(i-- works like i = i - 1 )
3 [ ] Array element (subscript) operator
4 ^ Exponentiation
5 - Negation - Unary minus
6 * Multiplication
7 / Division
8 % Reminder (Modulo operator)
9 + Addition
10 - Subtraction
11 < Less than
12 > Greater than
13 <= Less than or equal to
14 >= Greater than or equal to
15 == Equal to
16 != Not equal to
17 & Bit-wise "And" (AFL 2.1+)
18 | Bit-wise "Or" (AFL 2.1+)
19 NOT Logical "Not"
20 AND Logical "And"
21 OR Logical "Or"
22 = Variable assignment operator
