Operators

Operators are a combination of the following characters: ~ + - * / = > < & | ^, as explained in this section. There are four types of operators:

• Arithmetic operators require one or two numeric operands and produce a numeric result.
• Concatenation operators join two strings into a single string.
• Comparison operators require two operands and produce a Boolean (0 or 1) result.
• Logical operators require one or two Boolean operands and produce a Boolean result.

Each operator has an associated priority that determines the order in which operations will be performed in an expression. Operators with higher priorities (8) are performed before those with lower priorities (1).
