Operator Compatible types Description
+ Integer, Decimal, Text

For numerics, adds the lhs and rhs values and returns the result. For text values, concatenates lhs with rhs and returns the result:

var x = 45 + 3.3;

var y = 'hello' + ' world';
- Integer, Decimal

Subtracts rhs from lhs and returns the result:

var x = 4.04 - 3;
* Integer, Decimal

Multiplies lhs and rhs and returns the result:

var x = 34 * 0.993;
/ Integer, Decimal

Divides lhs by rhs and returns the result:

var x = 33 / 9.9;

Note that like C#, irScript uses integer division; this means that division of two integers always results in an integer return value. However, unlike C#, irScript supports division of integers by non-integers, and vice versa; in these cases,normal irScript type conversion rules apply (see below).
%

Integer,

Decimal

Divides lhs by rhs and returns the remainder:

var x = 100 / 5.3;

Note that irScript performs data type conversions during math operations, for integral numeric types. Note also that any floating-point representations later accessible outside irScript (in the InRule rule engine proper) are converted to System.Decimal.
