How to compare a decimal value with a integer in shell scripting?

Example:

i=1
j=1.2 
if [$j -gt $i];then
  echo "growth"
else
  echo "None of the condition met"
fi

Im getting output as None of the condition met

But i need output as growth,As 1.2 is greater than 1.

you should use bc (binary calculator).

i=1
j=1.2 
gt=$(echo "$j > $i" | bc -q )
# return 1 if true ; O if not
if [ $gt = 1 ]
then
   echo "growth"
else
   echo "None of the condition met"
fi
