Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, 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/) that was published on June 30, 2025. 

# Integer and floating-point literals
<a name="r_numeric_literals201"></a>

Literals or constants that represent numbers can be integer or floating-point.

## Integer literals
<a name="r_numeric_literals201-integer-literals"></a>

An integer constant is a sequence of the digits 0-9, with an optional positive (\+) or negative (-) sign preceding the digits.

## Syntax
<a name="r_numeric_literals201-synopsis"></a>

```
[ + | - ] digit ...
```

## Examples
<a name="r_numeric_literals201-examples"></a>

Valid integers include the following:

```
23
-555
+17
```

## Floating-point literals
<a name="r_numeric_literals201-floating-point-literals"></a>

Floating-point literals (also referred to as decimal, numeric, or fractional literals) are sequences of digits that can include a decimal point, and optionally the exponent marker (e).

## Syntax
<a name="r_numeric_literals201-synopsis2"></a>

```
[ + | - ] digit ... [ . ] [ digit ...]
[ e | E [ + | - ] digit ... ]
```

## Arguments
<a name="r_numeric_literals201-arguments"></a>

e \| E  
e or E indicates that the number is specified in scientific notation.

## Examples
<a name="r_numeric_literals201-examples2"></a>

Valid floating-point literals include the following:

```
3.14159
-37.
2.0e19
