熟悉我的都知道啊，这计算器已经迭代多次了。不浪费大家时间，只放一个上次的，有兴趣可以看看
0.1+0.2可以等于0.3！全FishC最好的计算器（不是），满足你对计算器的一切幻想 https://fishc.com.cn/thread-245235-1-1.html (出处: 鱼C论坛)]0.1+0.2可以等于0.3！全FishC最好的计算器
本期介绍
@isdkz @zhangjinxuan @sfqxx @不二如是 @python爱好者. @ba21 @KeyError @python爱好者. @小甲鱼的三师弟 @～风介～ @小甲鱼的二师兄 @鱼小二
可以注意到很多区别
全FishC最好的计算器！
消除误差！0.1+0.2可以等于0.3！
过大或过小的数值会用科学计数法
任选角度测量制度（默认角度制）
注意：
阶乘 ! 是括号之下优先级最高的运算
算术平方根运算后不加括号将只算数字
小数点后取7位（可调整），采用银行家舍入
【四舍六入五考虑，五后非空就进一，五后为空看奇偶，五前为偶应舍去，五前为奇要进一】
支持鼠标点击和键盘输入（非常神奇），但尽量不要混合使用
其中键盘输入 删除，回车，C有奇效。
输入0b, 0o, 0x前缀后回车或点击“＝”可以转换为十进制。计算的十进制结果可直接转换进制
还支持某些（奇怪）运算，如：√√√√65536（就是２），３！！（７２０）
甚至还可以动态调整运算精度
