There are 6 basic mathematical operators that can be used in Hugo templates:

| 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         |
| `ceil`    | Returns the least integer value greater than or equal to the given number.  | `{{ceil 1.1}}` → 2.0      |
| `floor`   | Returns the greatest integer value less than or equal to the given number.  | `{{floor 1.9}}` → 1.0     |
| `round`   | Returns the nearest integer, rounding half away from zero.                  | `{{round 1.1}}` → 1.0     |
