一、去除小数点
### --- 函数:

~~~     Ceil():四舍五入,向上取最接近的整数;比如2.79,向上取就是3
~~~     floor():四舍五入:向下取最接近的整数,比如2.79,向下取就是2
二、去除小数点,向上取四舍五入
### --- 函数:Ceil()

~~~     表达式:ceil(predict_linear(node_filesystem_files_free{mountpoint="/"}[1h],4*3600))
~~~     输出结果:49551911
三、去除小数点:向下取四舍五入
### --- 函数:floor:

~~~     表达式:floor(predict_linear(node_filesystem_files_free{mountpoint="/"}[1h],4*3600))
~~~     输出结果:49551909
