mongoexport返回科学(指数)表示法 [英] mongoexport returning scientific (exponential) notation

问题描述

因此，我使用mongoexport导出了一些集合，并发现了将9999999999999之类的大整数导出为9.9999999999999e+13

So I was exporting some collections using mongoexport and found cases where large integers such as 9999999999999 were exported as 9.9999999999999e+13

有两个问题:为什么会这样，如何防止这种情况?

So two questions: Why is this the case, and how can I prevent this?

谢谢.

推荐答案

MongoDB将所有数字文字视为

MongoDB treats all number literals as floating point by default, and above a certain threshold (32 bits?) it switches to scientific notation when exporting to JSON.
