通过对数据进行必要加工后的结果判断数据的存储方式，即，CPU的大端，小端-Through the data necessary to determine the results of processed data is stored, that is, CPU s big-endian, little-endian

大端模式存储的字节数据向浮点（单精度float、双精度double）、整型(int、long）转换类-Bytes of data stored in big-endian mode to the floating-point (single-precision float, double-precision double), integer (int, long) conversion class
