Arithmetic Operations

An expression in HCL DetectExpression Language can contain the basic arithmetic operations: addition (+), subtraction (-), multiplication (*), division (/), and modulo (%) with the usual semantics. These are binary operations that expect sub-expressions on each side. An expression in HCL Detect Expression Language can also contain the unary minus (-) operation that expects a sub-expression on the right. Finally, parentheses (()) are used for adjusting precedence, as usual.

Addition operation corresponds to concatenation for the String type and is the only available operation on this type. Bool type does not support arithmetic operations. Division applies integer division on integer types and floating point division on Double types.

The modulo operation yields the remainder from the division of the first operand by the second. It always yields a result with the same sign as its second operand. The absolute value of the result is strictly smaller than the absolute value of the second operand.

Examples:

A simple arithmetic expression: (3+4*5.0)/2
A simple expression involving a String literal: "area code\tcountry"
A unary minus expression: -(3+5.0)
