Why is Rounding Decimals Necessary?
Rounding of numbers in general is a method of estimation. Sometimes calculation becomes easier if we are ready to compromise on accuracy to a certain extent. That is where rounding decimals come in handy. I will give you a practical situation that will help you appreciate the benefits of rounding numbers better. Lets say you have a wall to be painted that has been outsourced to a local professional. The professional charges his rates on a per square meter of area painted. Why does he do so when he could have easily based his charges on every square centimetre he paints? The idea is simplicity in calculations. It will be much easier for him to calculate the area painted and the price to demand if he does his rates at per square meter basis rather than per square centimetre basis. Even if he paints 100 sq meters and 2 square centimetres of your wall he would charge you for 100 sq meters. In this case 2 sq centimetres become insignificant as compared to 100 sq meters and thus can be safel
