im trying to build something almost like a cashier system with php jquery and html so im confuse about the point system i got a simple input here :The input form
so the user will input their total price and base on that they'll get point , so for example user will get 1 poin every $10 , so when the user input $15 he's got 1 poin , and when the user input $13, he's still got 1 point, but when user input $20, he's gonna get 2 point , so thats basically thats how the system work, and my question is how to achieve that kind of system with php
