Precedence and associativity
If you combine several operands by using different operators, the operator precedence
defines in which order BI# will perform the operations. For example, BI# interprets
x + y * z as x + (y * z), because the operator * has a higher precedence than the operator +.
This table lists all operators sorted by their precedence from the highest to the lowest:
| Operators | Function |
|---|---|
+ - ! |
Unary |
* / % |
Multiplicative |
+ - |
Additive |
< > <= >= |
Relational |
== != |
Equality |
& |
Binary AND |
^ |
Binary XOR |

Associativity controls the order of operations, if you combine several operands by
using the same operator. For example, BI# interprets x + y + z as (x + y) + z, because the +-operator is left-associative. At the moment all operators in BI# are left-associative.
You can always change precedence and associativity by using parentheses as in (x + y) * z, for example.
