Why are the ceiling and the floor the same..?
35/2 = 17,5
ceiling of 17,5 = 18
35^0.5 = 5,916079783099616
floor of 5,916079783099616 = 5
I use ceiling and floor simply because even if it makes sense, stating that someone is 28,65465139 years old looks retarded ( I should even say it looks "matlab" xD ).
Well doing that :
age = floor (level/2+level^0.5+15) would also work but meh.
