My Command is below and its print Free CPU and Used CPU below format. 
I want to restrict awk output to 2 decimal place.

```
grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} {free=($5)*100/($2+$3+$4+$5)} END {print "Used Cpu:",usage "%"} {print "Free Cpu:",free "%"}'

```

Output : 

```
Free Cpu: 98.9588%

Used Cpu: 1.04125%

```

Desired output :

```
Free Cpu: 98.95%

Used Cpu: 1.04%

```
