有关此模型的用例,请参阅Numeric Model. For use cases of this model, see Numeric Model. What is the difference between Numeric and Decimal? Double及integer类型又被统一称为numeric 类型。 The integral types plus Float and Double are called numeric types. Variant(numeric )任何Double值一样大. Variant(numeric ) Any value as large as double. 当指定0以外的值时,将截断numeric_ expression。 When a value other than 0 is specified, numeric _expression is truncated.
Numeric 和decimal数据类型默认的最大精度是38。Maximum precision of NUMERIC and DECIMAL data types is increased to 34 digits. 在SQLServer中,numeric 数据类型等价于decimal数据类型。 In SQL Server, the numeric data type is equivalent to the decimal data type. Numeric display[n]:默认值可以符号和数字形式显示;.Numeric display[n]: The default is to have both a symbolic and numeric display;重要的第三方扩展的参考资料,比如Numeric 和TKinter. Reference material on important third-party extensions, such as Numeric and Tkinter. 从decimal或numeric 向float或real转换会导致精度损失。 Converting from decimal or numeric to float or real can cause some loss of precision. 如果省略function或其值为0(默认值),则将舍入numeric_ expression。 When function is omitted or has a value of 0(default), numeric _expression is rounded. 包含小数点和/或指数的常量总是首先被假定为类型numeric 。 Constants that contain decimal points and/or exponents are always initially presumed to be type numeric . 当一个数字直接出现在JavaScript程序中时,我们称它为数字直接量(numeric literal)。 When a number appears directly in a JavaScript program, we call it a numeric literal. 例如,常量12.345被转换为numeric 值,其精度为5,小数位为3。 For example, the constant 12.345 is converted into a numeric value with a precision of 5 and a scale of 3. 数字代码-用于货币的三位数字代码,由ISO3166-1numeric 标准分配。 Digital Code- the three-digit numeric code for the currency assigned by the ISO 3166-1 numeric standard. 举个例子,假设我们有一个user表,包括numeric ID(主键)和emailaddress。 For example, assume we have a usertable with a numeric ID(the primary key) and an email address. 从AutoClassifier、AutoNumeric 和AutoCluster三个自动建模方法中选择。 Choose from three automated modeling methods: Auto Classifier, Auto Numeric and Auto Cluster. 如果你更喜欢使用易读的plus的话,你可以给Ruby的内建Numeric 类添加一个函数。 If you would rather use the readable word plus, you could add such a method to Ruby's builtin Numeric class. 研究的四种技术分别是Numeric Outlier、Z-Score、DBSCAN和IsolationForest方法。 The four techniques we investigated are the numeric outlier, z-score, DBSCAN and isolation forest methods. 而能够节省出多少空间取决于你的数据库中含有多少decimal或numeric 数据列、数据分布情况以及表的大小。 How much space you save depends on the number of decimal or numeric columns, the data distributions, and the size of the table(s). 如果查询是自动参数化的,则将常量值转换为最终数据类型之前,始终先将其转换为numeric (10,0)。 When a query is autoparameterized, the constant value is always converted to numeric (10, 0) before converting to the final data type. 下面第一张图中,你可以看到OpenRefine可以用于运行Cuantía(Amount)里一项名为“facet”的数字型字段(numeric )。 In the first image below, you can see how Open Refine can be used to run a numeric “facet” in the Cuantía(Amount) field. 显然,如果设备的屏幕可以显示值,你可以观察到使用的Numeric Comparison或PasskeyEntry。 Obviously, if the devices have screens that can display a value and you can observe that Numeric Comparison or Passkey Entry is used, great. 对于decimal和numeric 数据类型,Microsoft®SQLServer™将精度和小数位数的每个特定组合看作是不同的数据类型。 For the decimal and numeric data types, SQL Server considers each specific combination of precision and scale as a different data type. 一定要设置OleDbParameter的类型、大小(如果适用)、以及精度和范围(如果参数类型是numeric 或decimal)。 Be sure to set the OleDbParameter type, size(if applicable), as well as precision and scale(if the parameter is of type numeric or decimal). 在Transact-SQL语句中,带有小数点的常量自动转换为numeric 数据值,且必然使用最小的精度和小数位数。 In Transact-SQL statements, a constant with a decimal point is automatically converted into a numeric data value, using the minimum precision and scale necessary. Numeric_ precisioncardinal_number如果这个域有一个数值类型,那么这个字段包含(声明的或隐含的)用于这个字段的类型精度。Numeric _precision cardinal_number If the domain has a numeric type, this column contains the(declared or implicit) precision of the type for this column.分析器里定义了几种类型范畴:boolean,numeric ,string,bitstring,datetime,timespan,geometric,network,和用户定义(user-defined)。 There are several basic type categories defined: boolean, numeric , string, bitstring, datetime, timespan, geometric, network, and user-defined. Visualbasic支持几种numeric 数据类型-integer(整型)、long(长整型)、single(单精度浮点型)、double(双精度浮点型)和currency(货币型)。 Visual Basic supplies several numeric data types- integer, long(long Integer) single(single- precision floating point), double(double-precision floating point), and currency.
