# negate

Returns the negation of the input value. This is a polymorphic function that preserves the input numeric type.

`negate(col)` is equivalent to the unary minus operator `-col`. See [Arithmetic Operators](/build-with-pinot/querying-and-sql/sql-syntax/sql-reference.md#arithmetic-operators) for operator syntax.

## Signature

negate(col)

| Argument | Type                                   | Description     |
| -------- | -------------------------------------- | --------------- |
| `col`    | INT, LONG, FLOAT, DOUBLE, BIG\_DECIMAL | Value to negate |

Returns the same type as the input argument.

## Usage Examples

```sql
SELECT negate(42.5) AS value
FROM myTable
```

| value |
| ----- |
| -42.5 |

```sql
SELECT negate(-10) AS value
FROM myTable
```

| value |
| ----- |
| 10    |

```sql
SELECT negate(100) AS int_neg, negate(1000000L) AS long_neg, negate(3.14F) AS float_neg, negate(2.718) AS double_neg
FROM myTable
```

Returns INT, LONG, FLOAT, DOUBLE respectively (preserving input type).
