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

If you want to round up, you need to perform the division as a floating point number, then call Math.Ceiling to get the next-highest whole number.

double quotient = Totallistcount / (double)perpagecount;
double ceiling = Math.Ceiling(quotient);
int totalpagescount = (int)ceiling;

Answer 3

这是整数除法应该如何工作，你需要先将它转换为double才能获得数字，然后使用Ceiling来“舍入”：

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

Answer 4

an other solution :

int pageCount = (records - 1) / recordsPerPage + 1;

int pageCount = (14 - 1) / 9 + 1; => pagecount = 2
