查询词典 precedence

Understanding expressions with multiple operators requires understanding operator precedence , associativity , and the order of evaluation of the operands.

要理解由多个操作符组成的表达式，必须先理解操作符的优先级、结合性和操作数的求值顺序。

Operator precedence defines how an expression evaluates when several operators are present.

运算符的优先级决定了存在多个运算符时一个表达式各部分的计算顺序。

The conditional operator has fairly low precedence.

条件操作符的优先级相当低。

The not operator has the highest precedence and is immediately one level below all the comparison operators.

not 运算符拥有最高优先级，只比所有比较运算符低一级。

Operator precedence follows the rules of algebra and may be altered by the use of parentheses.

操作符先要按照代数法则并且它可通过用来更改计算优先级。

The dereference operator has a higher precedence than the addition operator.

解引用操作符的优先级比加法操作符高。

The cast operator has the same high precedence as other unary operators, as summarized in the table at the end of this chapter.

强制类型转换运算符与其他一元运算符具有相同的优先级，表2-1对运算符优先级进行了总结。

The parser uses a proper operator precedence.

解析器采用适当的操作符的优先。

The basic function of the dynamic simulation algorithm is: Enter a given grammar, and FIRSTVT and LASTVT set output operator precedence analysis table generating algorithm output algorithm of table construction process priority main priority is based on the relationship between structure operator algorithm to draw priority relationship matrix.

动态模拟算法的基本功能是：输入一个给定文法，及FIRSTVT和LASTVT集；输出算符优先分析表生成算法；输出算法优先分析表构造的过程；主要是依据构造算符优先关系的算法来绘制优先关系矩阵表。

Scanning each character in the expression to separate and record operators, operational symbols and data types of operators, when expression being correct in syntax, recording interpreter executive order based on precedence of operator, a general expression interpreter is designed. The interpreter not only is used for numerical value and string computation, but also is easy to extend its functions, and when batch converting data, it could catch run error and continue to successive data.

2通过对公式的一次扫描，记录操作数、操作符号和操作数的赋值特性，并在语法正确的情况下，记录公式基于算符优先级的解释执行顺序，设计了通用公式解释器，它不仅可以进行数值运算、字符运算，而且可以对使用的函数库方便地进行扩充，在批量进行数据转换时，可以记录运行时错误，而不影响后续数据的执行。

Connectors are lines that can be anchored to particular places, called glue points , on the graphic object.

连接符，可固定在图形对象的特定的地方的线条。

Another way of putting it, too many agents have a say in each other's work, and bureaucratic rigor mortis sets in.

另一种表达是，太多的作用物在彼此的工作里都有话语权，官僚的僵尸开始抬头。
