compare decimal and integer values in if in bash shell
i need to do camparisions like the below.
For the case when first[1]=10 and second[1]=9.9 the scripts displays process failed.

I need to be able to convert the values to integer before doing the comparision.
Like 9.9 should be rounded over to 10 before doing comparision.

Please advice how can I do this.
Code:
for i in 1 2 3 4 5 6 7 8 9
do
  if [ ${first[i]} -gt `${seoond[i]} / 10` ]
  then
      echo "process failed "
      break
  fi
done
