寻呼机的页数

Question

I have X number of items and I want to count how many pages I'll need to page these items if I can put 5 items per page.

This is what I have:

int TotalPages = (int)(Math.Ceiling(TheItemCount / 5));

The line is underlined in red with an error that's saying there's an

ambigious call between Math.Ceiling (double) and Math.Ceiling (decimal)

I know this is supposed to be simple but I'm not getting the result I want. What do I need to change in my code to make it work?

Thanks.

Answer 1

The issue is that the compiler can't figure out which overload you want, so just force it to use the one of them:

int TotalPages = (int)(Math.Ceiling((double)TheItemCount / 5.0));

another way would be this:

int TotalPages = (int)(Math.Ceiling(Convert.ToDouble(TheItemCount / 5)));
