您要查找的是不是：
- explicit unary operator 显式一元算符
- An overloaded unary operator has no (explicit) parameter if it is a member function and one parameter if it is a nonmember function. 重载一元操作符如果作为成员函数就没有（显式）形参，如果作为非成员函数就有一个形参。
- A unary operator such as Minus is left as an exercise. 像负号这样的一元运算符就留给读者练习。
- Otherwise, the IIf function uses the unary operator of the child member. 否则,IIf函数将使用子成员的一元运算符。
- A definition of a unary operator where the argument is of the type of your class or structure. 一元运算符的定义,其中的参数是您的类或结构的类型。
- You declare two operands to define a binary operator, and you declare one operand to define a unary operator, including a type conversion operator. 声明两个操作数以定义一个二元运算符,声明一个操作数以定义一个一元运算符(包括类型转换运算符)。
- Returns a value generated by rolling up the values of the children of a specified member using the specified unary operator. 使用指定的一元运算符,通过汇总指定成员的子成员的值,从而返回所生成的值。
- 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. 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.
- The unary operator can be supplied by a member property associated with the child member, or the operator can be a string expression provided directly to the function. 一元运算符可通过与子成员关联的成员属性提供,也可以是直接提供给函数的字符串表达式。
- Unary operators have one parameter, and binary operators have two parameters. 一元运算符具有一个参数,二元运算符具有两个参数。
- A class that has a function-call operator and represents one of the unary operators, unary minus or logical NOT. 具有函数调用操作符且表示一个一元操作符的类，如一元减或逻辑非。
- In a unary operation in a mathematical system,one element is used to yield a single result. 在数学系统中的一元运算里，一个元素往往只产生一个单一的结果。
- Performs a unary operation that returns the negative value of a numeric expression. 执行一元运算,返回数值表达式的负值。
- Performs a unary operation that returns the positive value of a numeric expression. 执行一元运算,返回数值表达式的正值。
- The following table displays valid unary operators and describes the expected result. 下表显示了有效的一元运算符并说明了预期的结果。
- 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。
- Thus a subgroup of a group is a subset on which the binary product and the unary operation of inversion satisfy the closure axiom. 所以群的子群是在其上二元乘法和一元逆运算满足闭包公理的子集。
- He avoids the explicit answer to us. 他避免给我们明确的回答。
- He gave me explicit directions on how to get there. 他清清楚楚地告诉我怎样到达那里。
- She was quite explicit about why she left. 她对自己离去的原因直言不讳。
