XmlSchemaFractionDigitsFacet 类

定义

指定可以为 simpleType 元素的小数值输入的位数的限制。 fractionDigits 的值必须是正整数。 表示“万维网联合会”(W3C)fractionDigits 方面。

public ref class XmlSchemaFractionDigitsFacet : System::Xml::Schema::XmlSchemaNumericFacet
public class XmlSchemaFractionDigitsFacet : System.Xml.Schema.XmlSchemaNumericFacet
type XmlSchemaFractionDigitsFacet = class
    inherit XmlSchemaNumericFacet
Public Class XmlSchemaFractionDigitsFacet
Inherits XmlSchemaNumericFacet
继承

        <xs:restriction base="xs:decimal">
