0 is the result of how the shell decimal multiplication? : Cry : Ave=`expr "scale=2;6/17" |bc` #ave=.35 Sum = $ave\*100 #sum=0 Sum1 = `expr ${ave}\*100` #sum1=0 I think 35, how? Character is not because the avenue is stored. Will seniors, help me. 0 is the result of how the shell decimal multiplication? Expr can handle integer! Bc or accurate calculation using awk A=$ (echo "scale=2;6/17" |bc) Echo $a*100|bc 0 is the result of how the shell decimal multiplication? Upstairs predecessors, thank you so quickly reply to me. I tried, really good. Output 35.00 Results Is there no way to get 35, because I want to show the percentage% increase in the numerical behind. 0 is the result of how the shell decimal multiplication?
