又是一个固定宽度的整数（库）
yafwi的Python项目详细描述
yafwi
Yet Another Fixed Width Integer (Library)
Simple fixed with integers for developer experimentation.
Usage
Installation
Available through yafwi - PyPI使用pip install yafwi。在

方便的别名
^{pr2}$任意大小
>>>importyafwi>>>yafwi.generate_int(1024,unsigned=True)<class'yafwi.uint1024'>>>>yafwi.int512<class'yafwi.int512'>>>>yafwi.int3.max,yafwi.int3.min# Including some fun ones... (int3(3),int3(-4))
平台独立性
如果在大端系统上运行，与数字相关联的字节将不同，但是更高级别的功能应该保持不变。在
