XmlSchemaFractionDigitsFacet Class

Specifies a restriction on the number of digits that can be entered for the fraction value of a simpleType element. The value of fractionDigits must be a positive integer. Represents the World Wide Web Consortium (W3C) fractionDigits facet.

For a list of all members of this type, see XmlSchemaFractionDigitsFacet Members.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.


[Visual Basic, C#, C++] The following example shows the use of the XmlSchemaFractionDigitsFacet class.
