我的代码是基于Elements of Set Theory这本书,所以你可以先看看它的第5章,就是讲实数的戴德金分割的定义。另外提醒一下,这个项目只以传统教材的形式化为目标,而没有考虑其他的实用性,比如作为一个通用的库什么的。coq的标准库里面有更实用的实数构造法。

您好,非常感谢您的解答,我顺利的在coq标准库里发现了reals,但关于您说的实用性我还有些不太明白,这里的实用性是指用coq的标准库计算更快吗,还是说更方便构造新的type?再次表达对您分享的感谢!

或者说是泛用性吧。我不知道你要实数来做什么工作。我这里的实数是基于集合论的,你若采用了就只能在集合论里工作。而标准库里的实数是直接从类型论定义的,对你来说应该更容易理解

非常感谢您的指导!
