Arithmetic operators

The following table lists the arithmetic operators that ColdFusion supports:

String operator

The following table describes the one ColdFusion string operator that is a concatenation

operator:

>GT

GREATER THAN

Tests for greater than.

>= GTE,

GREATER THAN OR EQUAL TO

Tests for greater than or equal to

< > IS NOT, NEQ,

NOT EQUAL

Tests for nonequality.

CONTAINS Tests whether a value is

contained within a second

value.

DOES NOT CONTAIN Tests whether a value is not

contained within a second

value.

Operators Description

+, -, *, / The basic arithmetic operators: addition, subtraction, multiplication, and

division. In the case of division, the right operand cannot be zero.

+, - Unary arithmetic operators for setting the sign of a number either positive

or negative (+ or -).

Mod Returns the remainder (modulus) after a number is divided by a divisor.

The result has the same sign as the divisor. The right operand cannot be

zero; for example: 11 MOD 4 is 3.

\ Divides two integer values. Use the \ (trailing slash) to separate the

integers. The right operand cannot be zero; for example: 9 \ 4 is 2.

^ Returns the result of a number raised to a power (exponent). Use the ^

(caret) to separate the number from the power. The left operand cannot be

zero; for example: 2 ^ 3 is 8.
