I found this very cool code to get upload/download speed:

```
awk '{ if (l1) {
        print "↓"($2-l1)/1024"kB/s ","↑"($10-l2)/1024"kB/s"
    } else {
        l1=$2; l2=$10;
    }
}' <(grep wlan0 /proc/net/dev) <(sleep 1; grep wlan0 /proc/net/dev)

```

However, it returns up to 4 decimals. I rather have no decimals whatsoever. I have previously been able to round numbers using [bc](https://askubuntu.com/questions/217570/bc-set-number-of-digits-after-decimal-point) or [printf](https://stackoverflow.com/questions/13632001/how-to-display-number-to-two-decimal-places-in-bash-function), but I seem to only be able to use `print` in `awk`. What is a good solution to this issue?
