# Op Class Reference

> Terraform operators available via the Op class.

The `Op` class provides methods for performing logical and mathematical operations in Terraform expressions.

## Logical Operators

| Method | Signature                | Description             |   |       |
| :----- | :----------------------- | :---------------------- | - | ----- |
| `not`  | `Op.not(a: any)`         | Logical NOT (`!a`).     |   |       |
| `and`  | `Op.and(a: any, b: any)` | Logical AND (`a && b`). |   |       |
| `or`   | `Op.or(a: any, b: any)`  | Logical OR (\`a         |   | b\`). |
| `eq`   | `Op.eq(a: any, b: any)`  | Equality (`a == b`).    |   |       |
| `neq`  | `Op.neq(a: any, b: any)` | Inequality (`a != b`).  |   |       |

## Comparison Operators

| Method | Signature                | Description                       |
| :----- | :----------------------- | :-------------------------------- |
| `gt`   | `Op.gt(a: any, b: any)`  | Greater than (`a > b`).           |
| `gte`  | `Op.gte(a: any, b: any)` | Greater than or equal (`a >= b`). |
| `lt`   | `Op.lt(a: any, b: any)`  | Less than (`a < b`).              |
| `lte`  | `Op.lte(a: any, b: any)` | Less than or equal (`a <= b`).    |

## Mathematical Operators

| Method   | Signature                | Description               |
| :------- | :----------------------- | :------------------------ |
| `negate` | `Op.negate(a: any)`      | Unary negation (`-a`).    |
| `add`    | `Op.add(a: any, b: any)` | Addition (`a + b`).       |
| `sub`    | `Op.sub(a: any, b: any)` | Subtraction (`a - b`).    |
| `mul`    | `Op.mul(a: any, b: any)` | Multiplication (`a * b`). |
| `div`    | `Op.div(a: any, b: any)` | Division (`a / b`).       |
| `mod`    | `Op.mod(a: any, b: any)` | Modulo (`a % b`).         |
