Overview
B4P applies commonly practiced operator precedence rules when carrying out calculations with unary and binary operators. For example, multiplications and divisions are performed first before continuing with additions and subtractions.
| Precedence | Symbols | Description |
|---|---|---|
| 1 (highest) | +, -, ~, ! | All unary operators |
| 2 | *, / | Arithmetic operators: multiplication and division |
| 3 | +, - | Arithmetic operators: addition and subtraction |
| 4 | =, ==, <>, !=, >, >, <, <= | Comparison operators |
| 5 (lowest) | &, | | Logical operators |
The operators are described in the following section.
Parentheses
Parentheses can be used to overrule the operator precdences.
Examples
echo( 3 + 10 *2 + 100*4 ); // 423
echo( (3 + 10)*2 + 100*4 ); // 426
echo( 3 + 2 >= 2 + 2 ); // True
echo( 3 + (2 >= 2) + 2 ); // 6 (True in middle converts to 1)423
426
true
