这段代码输出的两行有可能不一样吗？解决方案

    float *lpfValue = (float*)(shared_memory + yc_offset);
        lpfValue += index;
        
        char *lpftmp = (char*)lpfValue;
        char *lptmp1 = (char*)(&fvalue);
        memcpy(lpftmp,lptmp1,sizeof(float));
        
        if(m_facno==1 && devno==3 && (index ==2 || index ==105))
        {
            printf("value%d =  %02X %02X %02X  %02X   %f \n ",index,lptmp1[0],lptmp1[1],lptmp1[2],lptmp1[3],fvalue);
            printf("value%d =  %02X %02X %02X  %02X   %f \n ",index,lpftmp[0],lpftmp[1],lpftmp[2],lpftmp[3],*lpfValue);
        }
