The simplest formula to calculate page count?

Question

I have an array and I want to divide them into page according to preset page size.

This is how I do:

private int CalcPagesCount() {     int  totalPage = imagesFound.Length / PageSize;      // add the last page, ugly     if (imagesFound.Length % PageSize != 0) totalPage++;     return totalPage; } 

I feel the calculation is not the simplest (I am poor in math), can you give one simpler calculation formula?

Answer 1

Force it to round up:

totalPage = (imagesFound.Length + PageSize - 1) / PageSize; 

Or use floating point math:

totalPage = (int) Math.Ceiling((double) imagesFound.Length / PageSize);
