XSD Numeric

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:decimal"/>

and an element in your XML document look like this:

<price>99.99</price>
<price>+99.1320</price>
<price>-99.1230</price>
<price>0</price>
<price>123</price>

Integer Data Type

The integer data type is used to specify a numeric value without a fractional component.

Let's see an example:

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

and an element in your XML document look like this:

<price>99</price>
<price>+999</price>
<price>-999</price>
<price>0</price>
