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.
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="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>
