If selected, a space is added before and after each binary operator.
It is a binary operator which needs two numerical values.
One of the parameters of a binary operator must be the containing type
When you break a long expression at a binary operator, the operator goes at the end of the previous line, e.g.,
当您在二元运算符处断开长表达式时,运算符将在前一行的末尾处运行,例如,
Formally, in the examples above we have two different operators that share the same symbol: the negation operator, a unary operator that reverses the sign, and the subtraction operator, a binary operator that subtracts one number from another.
严格地说,在上面的示例中,我们使用一个相同的符号表征了两个不同的运算符:负号运算符,即反转符号的一元运算符,减法运算符,是从另一个数减去一个数的二进制运算符。
Natural join (â<) is a binary operator that is written as (R â< S) where R and S are relations. The result of the natural join is the set of all combinations of tuples in R and S that are equal on their common attribute names.
自然连接是写为 (R ⋈ S )的二元运算 ,这里的R 和S 是关系。 [1] 自然连接的结果是在R 和S 中的在它们的公共属性名字上相等的所有元组的组合。
Similarly, we could define - (binary operator, means subtraction) or - (unary operation, means negation) or some other operators. I believe that it would be better to leave it for your exercise.
类似地,我们还可以为 Vector2D 定义像 - (减号,两个向量相减) ,- (负号,单个向量 x 和 y 同时取负) 等等这样的运算符。这个就作为练习交给大家。
