“一元运算符”是一种对单个操作数进行运算的运算符。
A unary operator is an operator that operates on a single operand.
一元运算符的定义，其中的参数是您的类或结构的类型。
A definition of a unary operator where the argument is of the type of your class or structure.
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。
Unary operators perform an operation on a single operand, such as returning the negative or positive value of a numeric expression.
使关系元组在由外存至主机的流动过程中就并行完成筛选、投影关系代数的一元运算。
When relational tuples are flowing from mass storage to host via this filter, the unary operations of relational algebra for them such as projection and selection are completed parallelly.
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。
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.
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）。
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).
注意数值型的字面值不包括符号(译注：正负号)，像-1实际上是个组合了一元运算符“-”和字面值1的表达式。
Note that numeric literals do not include a sign; a phrase like -1 is actually an expression composed of the unary operator '-' and the literal 1.

The unary minus (-) and unary plus (+) are the same operators as binary minus and plus.
群：二元结合运算为闭合的数学集合，具有单位元素。集合中每一元素都有逆元素。
Mathematics a set with an associative binary operation under which the set is closed, which contains an identity element and an inverse for every element in the set.
一元稀疏多项式的表示及运算。
在我们的四则运算表达式里面我们可以利用继承实行从一元到二元操作符的表示，但它实质上会干扰测试。
In our arithmetic expressions we could have used inheritance to get from a unary to a binary operator node, but that would substantially violate the test.
