irrational number
无理数
1. A real number that is not a rational number.
不属于有理数范围的一种实数。
2. A number such as 2 which can be shown to exist and upon which the operations defined upon the rational numbers can be shown to be defined, but which cannot be expressed as a quotient of a pair of integers.
诸如2这类数,可以证明它们的存在,也可以证明对有理数定义的运算对无理数也可定义。 无理数不能表示为两个整数的商的形式。 |
