操作数

When we do so, it should behave analogously to the synthesized operators: After an assignment, the values in the left-hand and right-hand operands should be the same and the operator should return a reference to its left-hand operand.

这样做时，它应表现得类似于合成操作符：赋值之后，左右操作数的值应是相同的，并且操作符应返回对左操作数的引用。

The right hand side has to mirror the type of the left hand side.

右操作数必须是左操作数的镜像。

A problem with adjusting the exponent of one operand so that it matches the exponent of the other operand is that we only have so many bits to use to represent the mantissa.

调整某个操作数的指数以使其匹配其他操作数指数的一个问题是，我们只有同样多的位数可用以表示尾数。

We can see that the operands to the multiplication operator are 10 and 20. The result of that expression and 2 are the operands to the division operator. The result of that division and 5 are the operands to the addition operator.

考虑优先级与结合性，可知该表达式先做乘法操作，其操作数为 10 和 20，然后以该操作的结果和 2 为操作数做除法操作，其结果最后与操作数 5做加法操作。

CF will be set to zero. If the operand is nonzero, CF will be set to one.

操作时操作数为0，则CF将被置为0；如果操作数不为0，则CF将被置为1。

So if an operand refers to data in the computer' s memory it is called an address.

所以，如果操作数用来指引计算机内存中的数据，则该操作数叫做地址。

If you change the value of an operand, don't use that operand elsewhere in the same statement.

如果要修改操作数的值，则不要在同一个语句的其他地方使用该操作数。

When you have an overflow you know that the second operand is greater than the first

当你发现出现了溢出时你就知道第二个操作数一定大于第一个操作数，因给结果一定

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。

Rank is the precedence of the operator, starting with 1 for addition..rpar is set for operators such as subtraction, which require their right operand to be enclosed in parentheses if it uses an operator of equal precedence.

rank 是运算符的优先级，从1递增。。rpar是为了像减号这样的运算符准备的，当减号遇到左操作数使用一个同优先级的运算符时，需要把这个左操作数用括号括起来，以使左操作数和减号结合起来。

And unto the angel of the church in Sardis write; These things saith he that hath the seven irits of God, and the seven star I know thy works, that thou hast a name that thou livest, and art dead.
