The DECIMAL and NUMERIC types store exact numeric data values. These types are used when it is important to preserve exact precision, for example with monetary data. In MySQL, NUMERIC is implemented as DECIMAL , so the following remarks about DECIMAL appl,The DECIMAL and NUMERIC types store exact numeric data values. These types are used when it is important to preserve exact precision, for example with monetary data. In MySQL, NUMERIC is implemented as DECIMAL , so the following remarks about DECIMAL appl, This means that the previous command creates a column that accepts values from -99.9999 to 99.9999. You may also create an UNSIGNED DECIMAL column, ranging from 0.0000 to 99.9999. For more information on MySQL DECIMAL the official docs are always a great,This section discusses the characteristics of the DECIMAL data type (and its synonyms), with particular regard to the following topics: Maximum number of digits. Storage format. Storage requirements. The nonstandard MySQL extension to the upper range of D,The maximum value of 65 for M means that calculations on DECIMAL values are accurate up to 65 digits. This limit of 65 digits of precision also applies to exact-value numeric literals, so the maximum range of such literals differs from before. (In older v,This section discusses the characteristics of the DECIMAL data type (and its synonyms), with particular regard to the following topics: Maximum number of digits. Storage format. Storage requirements. The nonstandard MySQL extension to the upper range of D,This tutorial shows you how to use MySQL DECIMAL data type to store exact values in decimal format. , 三者的区别介绍 float:浮点型，含字节数为4，32bit，数值范围为-3.4E38~3.4E38（7个有效位） double:双精度实型，含字节数为8，64bit数值范围-1.7E308~1.7E308（15个有效位） decimal:数字型，128bit，不存在精度损失，常用于银行帐目计算。（28个有效位） 按存储的范围进行排序 f., 另外一種可以儲存小數數值的「DECIMAL」型態就可以用來儲存完全精準的數值，儲存在這個型態中的數值，不論是查詢或是運算，都不會有任何誤差，不過「DECIMAL」型態佔用的儲存空間就比「FLOAT」和「DOUBLE」型態大。「DECIMAL」型態在MySQL還有一個一樣的關鍵字是「NUMERIC」，這兩種型態完全一樣。, 我们现在向大家介绍MySQL数据类型中DECIMAL类型的作用和用法，以及DECIMAL与FLOAT的比较，下面就请大家仔细阅读以下内容。
