这是一个简单的仿小米计算器的微信小程序, 目前比较简单, 仅供参考, 欢迎star。
计算器的逻辑是基于一个简单的状态机实现的, 下面给出了状态机图, 仅供参考。
- init: 初始状态
- first_undot: 第一个操作数录入中, 无小数点
- first_dot: 第一个操作数录入中, 有小数点
- second_undot: 第二个操作数录入中, 无小数点
- second_dot: 第二个操作数录入中, 有小数点
- result: 结果状态
- 支持简单的加减乘除和取余数
- 支持连续操作, 比如做了加法以后, 结果会直接作为第一个操作数进入下一轮操作
- 支持删除单个数字和一次性全部清空
