If you need to represent fixed point Numbers, such as dollars and cents, use BigDecimal instead.
如果需要表示定点数(譬如,几美元和几美分),则使用BigDecimal。
SQL-92 includes a decimal data type, which is an exact numeric type for representing fixed point decimal Numbers and performs basic arithmetic operation on decimal Numbers.
SQL- 92包括DECIMAL数据类型,它是用于表示定点小数的精确数字类型,它可以对小数进行基本的算术运算。
In Listing 2, I reopen the Numeric class (which handles both fixed and floating-point Numbers) to add the gram and pound methods.
在清单2中,我重新打开了numeric类(其处理固定和浮点数字)以便添加gram和pound方法。
And finally we prove that let a be a subset of real Numbers, if every continuous function which is defined on a and taken value in a has fixed point, then a is a finite closed interval.
最后还证明了对于实数的子集a,如果定义在A上取值于A内的任一连续函数都有不动点,则A为实数的有限闭区间。
Similarly, on platforms without native support for fixed-point or double-precision floating-point Numbers, implementations must emulate these types.
类似地,在没有本地定点或双精度浮点数支持的平台上,实现必须模拟这些类型。
You can also use a fixed-precision decimal type, or cast floating-point Numbers to a fixed-precision decimal type before you work with them.
您也可以使用固定精度的十进制类型,或者在使用浮点数之前将它们强制转换为固定精度的十进制类型。
Designers need to keep in mind the quantization errors that result from the fixed-point representation of Numbers on a fixed-point processor.
设计人员需要关注定点处理器中因定点数表示法而引起的量化误差问题。
