整数都是有理数对吗
有理数包括正整数、负整数、零和分数，但不包括无理数。这些数具有可以用分数形式表示的特点，同时也可以用小数表示，且小数部分有限或循环。有理数可不对，并不是所有的数都是有理数，在实数集范围内分为有理数，无理数两大集合，共同组成实数集，所有的整数，有限小数组成有理数集，所有的无限不循环小数构成无理数集，比如边为一的正方形，其对角线等于根号2就

数学上，有理数是一个整数a和一个正整数b的比，0也是有理数。有理数是整数和分数的集合，整数也可看做是分母为一的分数。有理数的小数部分是有限或为zheng shu yi ding shi you li shu shi dui de , kan lai lou zhu dui you li shu de ding yi bu shi hen ming que . shu fen wei : shi shu he xu shu shi shu fen wei : you li shu he wu li shu you li shu fen wei : zheng shu he fen shu zheng shu fen wei : zheng zheng shu , fu zheng shu he ling qi zhong zheng zheng shu he ling you jiao zi ran shu jie xi kan bu dong ? mian fei zha kan tong lei ti shi "
