Division can be tricky when it comes to programming and SQL. This is because computers strictly hold data types. What this means is that if in your scope the value you are referring to is an int it can only produce an int. This means that if you were to try to dived 5/2 you won't get 2.5 but instead you get 2 and the extra one will be the remainder. Where as had you divided 5.0/2 then you will get 2.5. So how do you ensure that the math is calculated correctly? Watch the video to find out.
