Note: pagination starts at page 1, not at page 0 (page(0) will return the same results as page(1)).
You can get page numbers or page conditions by using below methods.
```ruby
User.count #=> 1000
User.page(1).limit_value #=> 20
User.page(1).total_pages #=> 50
User.page(1).current_page #=> 1
User.page(1).next_page #=> 2
User.page(2).prev_page #=> 1
User.page(1).first_page? #=> true
User.page(50).last_page? #=> true
User.page(100).out_of_range? #=> true
```
