Solve : How do I store a real number into a variable??

1.	Solve : How do I store a real number into a variable??
Answer» Hi!! When I DIVIDE a number such as 20 / 100, the value that gets stored in a variable is just the integer part, i.e 0. I used var=`expr 20 / 100` Instead of storing 0.2, it stores 0. I need to USE the real value in further calculations. Please HELP...you can LOOK into bc command Code: [Select]echo 'scale=2;20/100' \| bc
