XSD Numeric Data Types


Decimal data types are used for numeric values.


Decimal Data Type

The decimal data type is used to specify a numeric value.

The following is an example of a decimal declaration in a schema:

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

An element in your document might look like this:

<price>999.50</price>

Or it might look like this:

<price>+999.5450</price>

Or it might look like this:

<price>-999.5230</price>

Or it might look like this:

<price>0</price>

Or it might look like this:

<price>14</price>


Integer Data Type

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

The following is an example of an integer declaration in a schema:

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

An element in your document might look like this:

<price>999</price>

Or it might look like this:

<price>+999</price>

Or it might look like this:

<price>-999</price>

Or it might look like this:

<price>0</price>
