| Function       | Description                                                                   | Example                          |
|----------------|-------------------------------------------------------------------------------|----------------------------------|
| `add`          | Adds two integers.                                                            | `{{add 1 2}}` → 3           |
| `div`          | Divides two integers.                                                         | `{{div 6 3}}` → 2           |
| `mod`          | Modulus of two integers.                                                      | `{{mod 15 3}}` → 0          |
| `modBool`      | Boolean of modulus of two integers. Evaluates to `true` if result equals 0.   | `{{modBool 15 3}}` → true   |
| `mul`          | Multiplies two integers.                                                      | `{{mul 2 3}}` → 6           |
| `sub`          | Subtracts two integers.                                                       | `{{sub 3 2}}` → 1           |
| `math.Ceil`    | Returns the least integer value greater than or equal to the given number.    | `{{math.Ceil 2.1}}` → 3     |
| `math.Floor`   | Returns the greatest integer value less than or equal to the given number.    | `{{math.Floor 1.9}}` → 1    |
| `math.Round`   | Returns the nearest integer, rounding half away from zero.                    | `{{math.Round 1.5}}` → 2    |
