## Numerical operators

The types `int`, `long`, and `real` represent numerical types. The following operators can be used between pairs of these types:

| **Operator** | **Description**  | **Example**                                      |   |
| ------------ | ---------------- | ------------------------------------------------ | - |
| `+`          | Add              | `3.19 + 3.19`, `ago(10m) + 10m`                  |   |
| `-`          | Subtract         | `0.26 - 0.23`                                    |   |
| `*`          | Multiply         | `1s * 5`, `5 * 5`                                |   |
| `/`          | Divide           | `10m / 1s`, `4 / 2`                              |   |
| `%`          | Modulo           | `10 % 3`, `5 % 2`                                |   |
| `<`          | Less             | `1 < 2`, `1 <= 1`                                |   |
| `>`          | Greater          | `0.23 > 0.22`, `10min > 1sec`, `now() > ago(1d)` |   |
| `==`         | Equals           | `3 == 3`                                         |   |
| `!=`         | Not equals       | `2 != 1`                                         |   |
| `<=`         | Less or Equal    | `5 <= 6`                                         |   |
| `>=`         | Greater or Equal | `7 >= 6`                                         |   |
