I would like to know if there is a way to express the "roundup" function of excel or "rounding off of a number to the nearest whole number" in an equation form. e.g. in excel: roundup $(2.13,0) = 3$, or just rounding off a number: $2.1 \Rightarrow 3$ or $32.9 \Rightarrow 33$.. etc.
I'm faced with a problem with an equation where only whole numbers should be involved to function correctly.
e.g. $\left(\frac{10}{3} - 1\right )$ is $(3.33 -1)$ but it should be $(4 - 1)$...
Thanks.
We use ceiling and floor functions, represented as brackets. So $\lceil 2.3 \rceil=3$ and $\lfloor 2.3 \rfloor =2$ Many computer languages use integer divide for integer variables, so $10/3=3$
