Amazon Redshift will no longer support the creation of new Python UDFs starting Patch 198. Existing Python UDFs will continue to function until June 30, 2026. For more information, see the [ blog post ](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/). 

# IS\_BIGINT function
<a name="r_is_bigint"></a>

Checks whether a value is a `BIGINT`. The IS\_BIGINT function returns `true` for numbers of scale 0 in the 64-bit range. Otherwise, the function returns `false` for all other values, including null and floating point numbers.

The IS\_BIGINT function is a superset of IS\_INTEGER.

## Syntax
<a name="r_is_bigint-synopsis"></a>

```
IS_BIGINT(super_expression)
```

## Arguments
<a name="r_is_bigint-arguments"></a>

*super\_expression*  
A `SUPER` expression or column.

## Return type
<a name="r_is_bigint-returns"></a>

`BOOLEAN`

## Examples
<a name="r_is_bigint_example"></a>

To check if `5` is a `BIGINT` using the IS\_BIGINT function, use the following example.

```
CREATE TABLE t(s SUPER);

INSERT INTO t VALUES (5);

SELECT s, IS_BIGINT(s) FROM t;

+---+-----------+
| s | is_bigint |
+---+-----------+
| 5 | true      |
+---+-----------+
```
