For the numeric values, the decimal data types are used.
XML Schema built-in data types:
The most common built-in data types of an XML Schema are:
- xs:string
- xs:decimal
- xs:integer
- xs:boolean
- xs:date
- xs:time
Decimal Data Type:
To specify a numeric value, we can use the decimal data type.
Example: Decimal declaration in a schema:
<xs:element name="cost" type="xs:decimal"></xs:element> |
An element in a document:
<cost>99.99</cost> |
Or:
<cost>+99.3132</cost> |
Or:
<cost>-99.3132</cost> |
Or:
<cost>0</cost> |
Or:
<cost>99</cost> |
Integer Data Type:
To specify a numeric value without a fractional component, the integer data type is used.
Example: Integer declaration in a schema:
<xs:element name="cost" type="xs:integer"></xs:element> |
An element in a document:
<cost>99</cost> |
Or:
<cost>+99</cost> |
Or:
<cost>-99</cost> |
Or:
<cost>0</cost> |
Numeric Data Types:
Except for the decimal itself, all the data types mentioned below are derived from the Decimal data type.

decimal | Used to define a decimal value. |
int | Used to define a signed 32-bit integer. |
integer | Used to define an integer value. |
long | Used to define a signed 64-bit integer. |
negativeInteger | Used to define an integer containing only negative values (..,-2,-1). |
nonNegativeInteger | Used to define an integer containing only non-negative values (0,1,2,..). |
nonPositiveInteger | Used to define an integer containing only non-positive values (..,-2,-1,0). |
positiveInteger | Used to define an integer containing only positive values (1,2,..). |
