Java Rouding off an integer

HI

I want to round off an integer to the next multiple of 10 in shell script.
(i.e.,) 91 should be rounded off to 100
and 90 should be rounded off to 90

It would be very helpful, if you can help me in this.

Thanks in advance

Supposing you have the value in a variable in a shell script:

Code:
var=91

round_var=echo "$var" | `awk '{printf("%d: %d\n",$0,int(($0+9)/10)*10)}'`

Regards

Hammer & Screwdriver Another approach

Code:
> var=90
> echo "($var+9)/10*10" | bc
90

> var=91
> echo "($var+9)/10*10" | bc
100

# 4  
much more simpler Smilie
Code:
echo "$(((var+9)/10*10))"

# 5  
Thank you very much..
