1. The problem statement, all variables and given/known data I need to approximate the number 14.45 to nearest integer. 2. Relevant equations 3. The attempt at a solution If I remember correctly, to approximate a decimal up to say 2nd decimal place, I look at the third digit and if this is greater than or equal to 5, then I increase the 2nd decimal place, otherwise keep the 2nd decimal digit as it is. e.g., 13.672 -> 13.67, 13.549-> 13.55 In my case what should I do? Should I first approximate to 1st decimal, then to nearest integer? Then should the answer be 14.45-> 14.5->15 Or is it operationally correct to note that .45<.5 so, 14.45->14? Which approach is correct?
