| `add`        | Adds two numbers.                                                           | `{{add 1 2}}` &rarr; `3`         |
|              | *If one of the numbers is a float, the result is a float.*                  | `{{add 1.1 2}}` &rarr; `3.1`     |
| `sub`        | Subtracts two numbers.                                                      | `{{sub 3 2}}` &rarr; `1`         |
|              | *If one of the numbers is a float, the result is a float.*                  | `{{sub 3 2.5}}` &rarr; `0.5`     |
| `mul`        | Multiplies two numbers.                                                     | `{{mul 2 3}}` &rarr; `6`         |
|              | *If one of the numbers is a float, the result is a float.*                  | `{{mul 2 3.1}}` &rarr; `6.2`     |
| `div`        | Divides two numbers.                                                        | `{{div 6 3}}` &rarr; `2`         |

|              | *If one of the numbers is a float, the result is a float.*                  | `{{div 6 4.0}}` &rarr; `1.5`     |
| `mod`        | Modulus of two integers.                                                    | `{{mod 15 3}}` &rarr; `0`        |
| `modBool`    | Boolean of modulus of two integers. Evaluates to `true` if result equals 0. | `{{modBool 15 3}}` &rarr; `true` |
| `math.Ceil`  | Returns the least integer value greater than or equal to the given number.  | `{{math.Ceil 2.1}}` &rarr; `3`   |
| `math.Floor` | Returns the greatest integer value less than or equal to the given number.  | `{{math.Floor 1.9}}` &rarr; `1`  |
