decimal arithmetic

Decimal arithmetic trap mask

十进制运算自陷屏蔽

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。

Let us look at parallels between arithmetic using binary numbers and arithmetic using decimal numbers.

我们采用与十进制运算对比的办法来介绍二进制数的运算方法.

Scaled decimal arithmetic fast-carry look-ahead arithmetic

带比例的十进算术运算快速超前进位算术运算

There are some cases where arbitrary-precision decimal arithmetic is still not sufficient to maintain exact results.

另外还有一些情形，任意精度的小数运算仍不能表示精确结果。

Here the engineer G. Stibitz had first only thought of designing relay machines to perform decimal arithmetic with complex numbers,

这里的工程师G.斯蒂比兹，一开始只想设计一台继电器机器，用来执行十进制的复数运算。

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。

That's more than adequate for most tasks, but you do need to keep in mind that it's not decimal arithmetic, and that every float operation can suffer a new rounding error.

但是，我们还是要牢记我们做的并不是十进制运算，任何一个浮点预算都有可能产生一个新的错误。

Let us look at parallels between arithmetic using binary numbers and arithmetic using decimal numbers. A Filter Design Method Based on Improved Aggressive

我们采用与十进制运算对比的办法来介绍二进制数的运算方法。基于改进渐进空间映射算法的滤波器设计

It varies from decimal in that precision decimal numbers carry not only a numeric value but also an arithmetic precision that is retained.

它与decimal不同，因为精度十进制数不仅包含一个数字值，而且保留了一个算法精度。
