本人代码：

#include "stdafx.h"#include <process.h>int _tmain(int argc, _TCHAR* argv[]){// 将十六进制转换为float形式unsigned char pMem[] = {0x66,0xE6,0xF0,0x42};float *p = (float*)pMem;printf("%g\r\n",*p);// 将float转换为16进制float a=120.45f;unsigned char * b = (unsigned char*)&a;for(int i = 0; i<4; i++) printf("0x%2X,", b[i]); system("pause");return 0;}
