十进制数据类型支持,用于对货币/货币值进行类似于COBOL的定点运算。 作者:Piotr Likus 创建于:2011年3月1日 修改时间:20/04/18 许可证:BSD 版本:1.18 此数据类型旨在通过即时舍入进行计算并支持正确的比较功能(浮点比较不可靠)。 值使用64位整数在内部存储,因此最大位数为18。 精度是用户定义的,因此可以将此数...

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. (There is also a limit on how long the text...

dec - for Decimal Base format oct - for Octal Base format hex - for Hexadecimal Base format Example 1In this example, we will print (write) the value of a variable named var (the value of var is 100 in Decimal Base format) in Octal Base format, Decimal Base format and...
The declaration syntax for a DECIMAL column is DECIMAL(M,D). The ranges of values for the arguments are as follows: M is the maximum number of digits (the precision). It has a range of 1 to 65. D is the number of digits to the right of the decimal point (the scale). It has ...
