How can I remove the zero that appears after the decimal point

I have declared two float variables for addition purpose...

So, the user can input 2.2+2.2 and get 4.4 And sometimes the user will enter 2+2 and will get 4.0>> this zero needs to be deleted.

I can't use the round method nor converting the whole result into an integer.

My Actual code is here:

holder.txtTotalViews.setText(new StringBuilder().append(new java.text.DecimalFormat("#").format(Float.parseFloat(trendingVideoList.get(position).getTotal_views())/1000)).append("K ").append(activity.getString(R.string.lbl_views)));

I need to calculate total views of video into K format like 10K and 10.5K. I have problem to remove zero from 10.0K.

My Issue is resolved by changing decimal format of the code: Thanks to @Jyoti now my code:

I need to change my new java.text.DecimalFormat("#") to new java.text.DecimalFormat("#.#") like this.

holder.txtTotalViews.setText(new StringBuilder().append(new java.text.DecimalFormat("#.#").format(Float.parseFloat(trendingVideoList.get(position).getTotal_views())/1000)).append("K ").append(activity.getString(R.string.lbl_views)));

You can make a common function like this:

// No need to re-create decimal format instance. Keep this outside of the function.
DecimalFormat decimalFormat = new DecimalFormat("#.#");
public String numberToString(float number){
    if(number == (int) number){
        return Integer.toString((int) number);
    }
    return decimalFormat.format(number);
}
