# XSD Numeric Data Types

 « Previous Chapter Next Chapter »

Decimal data types are used for numeric values.

## Decimal Data Type

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

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



An element in your document might look like this:

 767.23

Or it might look like this:

 +767.2311

Or it might look like this:

 -767.1121

Or it might look like this:

 0

Or it might look like this:

 14

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 Below is an example of an integer declaration in a schema:



An element in your document might look like this:

 767

Or it might look like this:

 +767

Or it might look like this:

 -767

Or it might look like this:

 0
