How to always get a whole number if we divide two integers in c#

Question

I have three integer type variable

1. Totallistcount
2. totalpagescount
3. perpagecount

Suppose at initial level i have this

Totallistcount = 14;
perpagecount = 9;

Now I have a formula to found total number of pages possible

totalpagescount = Totallistcount / perpagecount ;

but in this situtation I got 1 in totalpagescount but I need 2 in totalpagescount , because 9 items on the first page and rest of item will be displayed on last page , How can I do this

Thanks ,

Answer 1

totalpagescount = (Totallistcount + perpagecount - 1) / perpagecount ;

Answer 2

This is how integer division should work, you need to convert it to double first to be able to get the number and then use Ceiling to "round it up":

(int)Math.Ceiling( (double)Totallistcount / perpagecount);
