Decimal data types are used to represent numbers in XML documents.

Decimal Data Type

The decimal data type (<xs:decimal>) is used to represent numeric values. It supports decimal numbers up to 18 digits.

Let's see an example:

<xs:element name="price" type="xs:integer"/>

and an element in your XML document look like this:
