3/2 is 1. Not 1.5, but 1. This is what I was actually taught by one of my maths teachers, who is a Dr of Particle Physics, you even get taught his theories if you do a doctorate in Physics, but yeah, 3/2 is 1, because you always give the answer to the same amount of decimal places. I was always taught that halfway values (.5) are rounded up but when I looked that up I found out that you can round them either up, to zero, half to even or stochastically. I. {censored}ing. Hate. Math.
