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="prize" type="xs:decimal"/>

An element in your document might look like this:

<prize>999.50</prize>

Or it might look like this:

<prize>+999.5450</prize>

Or it might look like this:

<prize>-999.5230</prize>

Or it might look like this:

<prize>0</prize>

Or it might look like this:

<prize>14</prize>

Note: The maximum number of decimal digits you can specify is 18.

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="prize" type="xs:integer"/>

An element in your document might look like this:

<prize>999</prize>

Or it might look like this:

<prize>+999</prize>

Or it might look like this:

<prize>-999</prize>

Or it might look like this:

<prize>0</prize>

Note that all of the data types below derive from the Decimal data type (except for decimal itself)!
