Keep 2 digits after the decimal point.

[tyf2018]

I use this code to list all files in the current directory, and the file size I want to be in KB, so I divided by 1024, but the result is too many digits after the decimal point.

```dataviewjs
var n = luxon.DateTime.now();
var format = dv.current().dateformat || 'yyyy-MM-dd';
var locale = dv.current().locale || 'zh';
dv.table(
    ['笔记名','文件大小', '上次编辑', '路径'],
    dv.pages()
        .where(p => p.file.name != dv.current().file.name
            && p.file.folder.includes(dv.current().file.folder))
        .sort(p => p.file.folder, 'asc')
        .map(p => [
            p.file.link,
   	    p.file.size / 1024,
	    p.file.mtime.toRelative({locale:locale,unit:'days'}),			
            p.file.folder])
)
```

So I want to keep only 2 digits after the decimal point.

I found this command in the user guide, but I don’t know how to add it to the original code correctly.

round(number, [digits])

Hope someone can give me some pointers, thank you!

That is a Dataview Query Language function, but you can call it from Javascript as dv.func.round(number, 2).

.dv.func.round(number, 2)

Thank you, but I don't know where to put .dv.func.round(number, 2).

I am sorry that I have almost no knowledge of js. I tried several positions and kept getting an error.🤣

It's a function, so it goes around the value you want to round - p.file.size / 1024 in this case: I've included it in the updated source here:

```dataviewjs
var n = luxon.DateTime.now();
var format = dv.current().dateformat || 'yyyy-MM-dd';
var locale = dv.current().locale || 'zh';
dv.table(
    ['笔记名','文件大小', '上次编辑', '路径'],
    dv.pages()
        .where(p => p.file.name != dv.current().file.name
            && p.file.folder.includes(dv.current().file.folder))
        .sort(p => p.file.folder, 'asc')
        .map(p => [
            p.file.link,
   	    dv.func.round(p.file.size / 1024, 2) + "KB",
	    p.file.mtime.toRelative({locale:locale,unit:'days'}),			
            p.file.folder])
)
```
