Hi all!
When converting a decimal to a time in physical applications of calculus, do we round up or down?
For example, say your answer is 2.885 years (where year 0 = 2008), but the question wants the answer as a year and months. So we convert the 0.885years to a month and we get 10.6 months.
My question is, does this then go down as October or November? The event will take place in October, but normal rounding rules would bring it up to November.
Thanks!
