To create a decimal type, you specify the precision and, optionally, the scale for the data to be stored.
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。
If you've never encountered an exact precision data type, the distinction between a decimal and floating-point type may be confusing.

Derby provides support for real Numbers in several formats: single-precision floating-point, double-precision floating-point, and an exact representation decimal, as presented in Table 2.
Derby对实数提供了多种格式的支持：单精度浮点、双精度浮点以及准确的算术表示，如表2所示。
These are based on the IEEE 754 standard, which defines a binary standard for 32-bit floating point and 64-bit double precision floating point binary-decimal Numbers.
它们都依据IEEE 754标准，该标准为32位浮点和64位双精度浮点二进制小数定义了二进制标准。
One takes a double-precision floating point as input, another takes an integer and a scale factor, and another takes a String representation of a decimal number.

速，两位整数一位小数的显示方式具有更高的显示精度。
BigDecimal is a standard class, with no special support in the compiler, to represent arbitrary-precision decimal Numbers and perform arithmetic on them.
BigDecimal是标准的类，在编译器中不需要特殊支持，它可以表示任意精度的小数，并对它们进行计算。
Internally, BigDecimal is represented as an arbitrary-precision unscaled value and a scale factor, which represents how many places to move the decimal point left to obtain the scaled value.
在内部，可以用任意精度任何范围的值和一个换算因子来表示BigDecimal，换算因子表示左移小数点多少位，从而得到所期望范围内的值。
For example, a business user might not know that double means a double-precision decimal.
例如，业务用户可能不知道double表示双精度小数。
