How to nicely format floating types to String?
I have number:
Double d1=(Double)0; Double d2=(Double)2.2; Double d3=(Double)4; When I use to String, I get 0.0, 2.2, 4.0, but I want to see 0, 2.2, 4. How can I do it?

Use DecimalFormat.format insted of Double.toString:
Double d1 = (Double)0.0; Double d2 = (Double)2.2; Double d3 = (Double)4.0; // Example: Use four decimal places, but only if required NumberFormat nf = new DecimalFormat("#.####"); String s1 = nf.format(d1); // 0 String s2 = nf.format(d2); // 2.2 String s3 = nf.format(d3); // 4 You don't even need Doubles for that, doubles will work just fine.

First Convert your Double to String with String.valueof(YOUR_VARIABLE)
then Use Below Function to do it.
private String getyourNumber(String NUMBER) { if(!NUMBER.contains(".")) { return NUMBER; } return NUMBER.replaceAll(".?0*$", ""); } then Convert your
String to Double with
Double.parseDouble(YOUR_RETURNED_STRING).
