## Unary Minus Operator:
|
||||
Negative numbers are supported via the unary minus operator. Positive numbers are not explicitly supported as unsigned numbers are assumed positive.
|
||||
|
||||
## String Support:
|
||||
Expressions can contain double or single quoted strings that are evaluated the same way as PHP evalutes strings as numbers. You can also pass strings to functions.
