工具介绍
一桌人吃完饭，账单上还带着服务费和小费，人均多少最容易算错。填金额和人数，每人该付多少直接给出来。 A shared meal with a service charge and tip on top is where the per-head maths usually goes wrong. Enter the amount and head count to get each share.
差几分钱的情况也处理：保留两位小数时差额落在最后一位，抹零到元时每人向上取整、多收多少单独列出。 Cents are handled too: with two decimals the difference lands on the last person, and with rounding up each share goes to whole yuan while the surplus is listed separately.

常见问题
服务费和小费叠加吗？Do service charge and tip stack?
是，先加服务费，再对含服务费的金额算小费。Yes — service first, then the tip applies to the amount including service.
为什么有一人多付几分钱？Why does one person pay a few cents more?
除不尽的分位差额只落在最后一位，避免每个人都差一分。The indivisible cents land on the last person only, so nobody is a cent short.
抹零到元多收的钱去哪了？Where does the rounding surplus go?
单独列出，可以留作小费或多点一份。It is listed separately — keep it as tip or order one more item.
支持每人点单不同吗？Does it handle itemised orders?
不支持，只按总额均摊。No, it splits the total evenly.
