已知气压，温度，求当前高度的公式。

通过该公式，实现的C语言代码：

float  BMP_Temperature,BMP_Pressure,Altitude;
    while(BMP280_GetStatus(BMP280_MEASURING) != false);
    while(BMP280_GetStatus(BMP280_IM_UPDATE) != false);
    BMP_Temperature = BMP280_Get_Temperature();
    BMP_Pressure = BMP280_Get_Pressure();
    printf("温度：%.2f C 压强：%.2f Pa\r\n",BMP_Temperature,BMP_Pressure);
    Altitude = ((powf((101325.0f/BMP_Pressure),(1/5.257f))-1) * (BMP_Temperature+273.15f)) / 0.0065f;
    printf("高度:%.4fcm\r\n",Altitude);
