要创建算术类型，应当指定保存的数据的精度，并可选地指定数据的刻度。
To create a decimal type, you specify the precision and, optionally, the scale for the data to be stored.
price列创建为DECIMAL数据类型，精度为5，刻度为2。
The price column is created as a DECIMAL data type with a precision of 5 and a scale of 2.
默认情况下，decimal类型的刻度为0，这意味着DECIMAL数据类型模拟了整数类型。
By default, the scale for a DECIMAL type is 0, which means the DECIMAL data type mimics an integer type.
外刻度（图6）-这个刻度是测微计类型刻度，在红手轮的锥形底座上标注0 - 9。
Outer Scale (Fig. 6) - This scale is a micrometer-type scale marked 0-9 at the tapered base of the red handwheel.
