浮点型(FLOAT)与CHAR型转换

浮点（FLOAT）转换为CHAR

  float wTemp=3.3;
   char sBuf[4];
   char* temp;
   memset(sBuf,0,sizeof(sBuf));
   temp=(char*)(&wTemp);
   sBuf[0] = temp[0] ;
   sBuf[1] = temp[1];
   sBuf[2] = temp[2];
   sBuf[3] = temp[3]; 

CHAR转换为浮点（FLOAT）

  char sBuf[4];
  sBuf[0]=0x33;
  sBuf[1]=0x33;
  sBuf[2]=0x53;
  sBuf[3]=0x40;
  float *w=(float*)(&sBuf);
