//For those of you that don't get it this technique is called scaling. Basically what the answer does here is bring two figures across the decimal point turning the figure into a whole number to avoid all the crazy floating point issues, round that and then translate it back into what it was before by dividing by 100 and you have your answer to 2dp.
