    read -p "Enter the expression: " exp
printf "%.3f" $(echo $exp | bc -l)

    where 1st line will take the expression, and 2nd line will read the expression using echo $exp, perform the calculations using bc -l and print the result upto 3 decimal places using printf "%.3f"

    read x
var=$(echo "scale=4; $x" | bc)
printf "%.3f\n" "$var"

    The simplest solution:

    printf "%0.3f" $(cat - | bc -l)

    cat - reads a numeric value from standard input (stdin).

    | pipes the input to the next command.

    bc -l performs arbitrary-precision calculations, including math functions like sine and cosine.

    $(...) captures the result of the bc calculation.

    printf "%0.3f" formats and prints the captured result as a floating-point number with three decimal places.

    In summary, this code reads a number, performs a mathematical operation, and displays the result with three decimal places.

    read number
new_number1=$( echo "scale=4; $number " | bc)
new_number2=$( echo "scale=3; $number " | bc)
last1=${new_number1: -1}
last2=${new_number2: -1}
if(( last1 < 5)); then
    echo $new_number2
else
    if(( last2 < 9 )); then
        last2=$((last2+1))
    fi    
    new_number2=${new_number2:0:-1}$last2
    echo $new_number2
fi
