Hi Friends,
I need a help again in awk.
I just need to round up a value.

Eg Say x=5.664584525
I need to display x=5.66 means round. How can i do round in UNIX.

Use the printf format "%.2f" to perform rounding.
e.g.
echo "5.664584525" | awk '{printf "%.2f",$0}'
output will be 5.66

Hi Friends,

Can any one please give the following solution.

Say I have a variable x = 8/3

I need the value of x as 2.66.

And I am using the same in shell script.

Can I get the above value with round function or awk command.

Thanks in advance friends.

8/3 = 2.666666... rounded to 2 decimals is normally 2.67

b = `echo "8/3" | bc -l`
printf ".2f\n" $b

printf does rounding for you

Through shell?

echo "scale=2; 8/3"|bc
