Ah yes, the classic pagination system that absolutely nobody uses. Those suspiciously precise version numbers masquerading as page numbers? That's what happens when the backend developer is also in charge of UI design.
Nine decimal places of precision for page numbers is exactly what users need! And that "Go" button? It's just sitting there, judging your life choices, knowing damn well nobody's typing "page 3.023809523809" in that input field.
This is what happens when you ask for "pagination" in the requirements doc without specifying further details. The developer technically delivered what was asked for... just with the UX sensibilities of a calculator.
