To expand on Uri's comment, see "float and real (Transact-SQL)"https://msdn.microsoft.com/en-us/library/ms173773.aspx: Approximate-number data types for use with floating point numeric data. Floating point data
Monetary data represents positive or negative amounts of money. In Microsoft® SQL Server™ 2000, monetary data is stored using themoneyandsmallmoneydata types. Monetary data can be stored toan accuracy of four decimal places.Use thesmallmoneydata type to store values in the range from -214...

INSERTINTOfinancial_records(transaction_amount)VALUES(12345.67); 如果小数位数超过2位,此时将会进行四舍五入,最终只会保存2位小数,示例如下: mysql>INSERTINTOfinancial_records (transaction_amount)VALUES(12345.688); Query OK,1rowaffected,1warning (0.03sec) ...
SQL SERVER FLOAT 运算精度 sql数据类型的长度和精度 一、SQL基本操作 1.1、 数据类型 字符型:varchar2(最常用的 长度可变的字符串)char(定长)ncharnvarchar2(unicode字符集变长字符型数据)long(使用比较少) 数字型: number(p,s)p表示精度,s表示保留小数最大精度38位...
Note:SQL Server treatsn as one of two possible values.If1<=n<=24,n is treated as24.If25<=n<=53,n is treated as53. 2,在SQL Server中,小数常量的默认数据类型是decimal,decimal的优先级比float高。 In Transact-SQL statements, a constant with a decimal point is automatically converted into ...
CREATE TABLE floating_point_values ( id INT AUTO_INCREMENT PRIMARY KEY, small_float FLOAT, large_float FLOAT, small_double DOUBLE, large_double DOUBLE ); 在floating_point_values的表,其中包含了四个列,具体含义如下: small_float:用 FLOAT 类型来存储非常小的数值。
使用SqlServer中的float类型时发现的问题 使⽤SqlServer中的float类型时发现的问题 在做项⽬中，使⽤了float类型来定义⼀些列，如：Price，但是发现了很多问题 1、当值的位数⼤于6位是float型再转varchar型的时候会变为科学技术法显⽰ 此时只好将float型转换成numeric型，再转换成varchar 2、float型变量在...
Approximate-number data types for use with floating point numeric data. Floating point data is approximate; therefore, not all values in the data type range can be represented exactly. The ISO synonym for real is float(24).Transact-SQL syntax conventionsSyntax...
