Java double type conversion to degrees minutes seconds

Java double type conversion to degrees minutes seconds

The java double type is converted to the form of degrees, minutes, and seconds. This is often used in latitude and longitude. Not much else to say directly to the code

   public static String dblToLocation(double data) {
    
    
        StringBuffer result = new StringBuffer();
        //得到度
        int du = (int) data;
        result = result.append(String.valueOf(du) + "°");
        //得到分
        double du1 = data - du;
        int min = (int) (du1 * 60);
        result = result.append(String.valueOf(min) + "′");
        //得到秒
        double min1 = du1 * 60 - min;
        int sec = (int) (min1 * 60);
        result = result.append(String.valueOf(sec) + "″");
        return result.toString();
    }
