Question

Trying to figure out an equation to get the current group a page would be in if they were grouped like below.

Variables:

PageSize = 5 PageIndex = 21 GroupSize = 5 TotalItems = 1000 CurrentPage = PageIndex + 1 

Find:

**CurrentGroup = ?** 

If there are 1000 items and you have a group size of 5 then there are 200 groups (TotalItems / GroupSize). This means that CurrentPage 22 must land in group 5

Group 1: 1 2 3 4 5 Group 2: 6 7 8 9 10 Group 3: 11 12 13 14 15 Group 4: 16 17 18 19 20 Group 5: 21 22 23 24 25 

Answer 1

Formula

1+floor((CurrentPage-1)/GroupSize) 

Test

1 -> 1  ..  5 -> 1  6 -> 2  ..  9 -> 2 .. 22 -> 5
