代码工作不正确，显示无法理解的数字:3.612432554629948e + 76显示不可理解的值，它应该是这样的:并应输出:大量，例如:十六进制:8459 f630cd86ddfa329b3d13d5217d45df1d5e9a56a63f6a3d7ab8b794c35c1212月:59864244547079690871082685810675850360550404961977540588162601013229404773394

不确定为什么在hexToDec方法中将转换值除以2**21:
return str(i/float(2**21))
不需要除法，只要输入
就可以得到正确的输出。return str(i)
直接从你的hexToDec方法。
