Hi,
in my ksh script

expr 22 / 10 results as 2
but the actual result expected in 2.2.
how do i get that result. Please help

Thanks,

/ is integer division
% modulus
may be you can use awk

awk 'BEGIN{print (22/10) }'

with parameters

awk -v a=$1 -v b=$2 '{print (a/b) }'

or

echo $number |awk '{print ($1/10)}'

expr works with integers.

Code:

 # echo 'scale=2;22/10' |bc
2.20
