C语言字节如何转换成MB？

#include "stdafx.h"
#include "windows.h"
#include "stdio.h"
int main()
{
DWORD FileSize;

HANDLE FileHandle=CreateFile("123.exe",GENERIC_WRITE,0,NULL,OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);

FileSize=GetFileSize(FileHandle,NULL);

printf("%d 字节\n",FileSize);

return 0;
}

1024字节=1K字节
1024K字节=1M字节
printf("%.2fM字节",(float)FileSize/1024/1024);

10进制转2进制，除2就可以了
