如果一个操作数是无符号整数，另外一个操作数是有符号整数，那么表达式的结果就是无符号整数。
If one of the operands is unsigned and the other is a signed int, the expression becomes an unsigned.
扫描程序读取缓冲中的单个字符并返回解析器能理解的记号(称做标记)——如关键字、操作符及针对特定语言的标点符号。
A scanner reads in the individual characters of a buffer and returns symbols (called tokens) that the parser will understand — such as keywords, operators, and language-specific punctuation.
表示双目运算符(binaryoperator)的UML操作的命名方式类似于单目运算符，但符号是双目运算符之一。

在OmniFind 中，与该概念关系最密切的映射是-符号，其在大多数情况下是可用于搜索的 “异”运算操作符，但是不会生成它自己的结果。
In OmniFind, the closest mapping to this concept is the - symbol, which is more of an exclusion operator that can be applied to the search, but will not generate results of its own.
如果我们能够确定其中的一个操作数为unsigned，那么使用无符号除法将会更好，因为它要比有符号除法快得多。
