Mongodb聚合框架中是否有地板功能?
我尝试在 mongodb 中进行一些整数数学运算，但遇到了一些问题.有没有办法在 mongo db 聚合框架中向上或向下舍入双精度数?
I try to do some integer math in mongodb and have some problems. Is there a way to round doubles up or down in the mongo db aggregation framework?
推荐答案
根据 Stennie 的评论，不支持 floor 和 ceiling 方法.
As per the comment from Stennie, the floor and ceiling methods are not supported.
根据我上面的评论，我能找到的最佳解决方案就是执行如下所示的操作: (num-mod(num,1)) 应该产生与 floor 函数相同的结果.
And as per my comment above, the best solution that I could find was just doing an operation that looks like: (num-mod(num,1)) which should yield the same result as the floor function.
