If t=s, the binary operation is said to be closed . 当TS时,二元运算叫做封闭的运算。
In this and next section, we shall consider some particular algebraic sets having binary operations defined on them . 在这一节及下一节中,我们将讨论一些在其定义为二元运算的特殊代数集合。
If t = s , the binary operation is said to be closed 当t s时,二元运算叫做封闭的运算。
Addition , subtraction , multiplication , and division are binary operations 加、减、乘、除都是二元运算。
When performing binary operations , if one of the operands is a floating - point type , 在执行二进制运算时,如果一个操作数为浮点类型(
In mathematics, a binary operation on a set is a calculation involving two elements of the set (called operands) and producing another element of the set (more formally, an operation whose arity is two). Examples include the familiar elementary arithmetic operations of addition, subtraction, multiplication and division.
