Unary operators have one parameter, and binary operators have two parameters.
一元运算子有一个参数，而二元运算子则有两个参数。
Unary operators perform an operation on a single operand, such as returning the negative or positive value of a numeric expression.
一元运算符对单个操作数执行操作，如返回数值表达式的负值或正值。
The power operator binds more tightly than unary operators on its left; it binds less tightly than unary operators on its right. The syntax is.
幂运算符比在操作数左边的一元运算符有更高的优先级；但比右面的一元运算符要低。句法为。
Thus, in an unparenthesized sequence of power and unary operators, the operators are evaluated from right to left (this does not constrain the evaluation order for the operands).
因此，在一串没有括号的由幂运算符和一元运算符组成的序列，会从左到右面求值（没有强制改变求值顺序）。
A UML operation representing a binary operator is named similarly to unary operator, but the symbol is one of the binary operators.
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。
The unary minus (-) and unary plus (+) are the same operators as binary minus and plus.
一元减号(-)和一元加号(+)与二元加号和减号都是相同的运算符。
In addition to the unary tests above, you can compare two files with the binary operators shown in Table 2.
除了上面的一元测试以外，你也可以通过一对操作符来对两个文件进行比较，如表2。
