How can I round numbers (2 decimal) parseXml get(field) in Android

Question

TextView.setText(XMLdata.get("XMLField") + " mm");

input values that are expressed in an abbreviated way:

10,5858555966668 (with comma)

Which I would like to convert into:

10,58

Answer 1

if your XMLdata.get("XMLField") value is float u can do the following code

String finalValue = String.format(
                    "%.2f", XMLdata.get("XMLField"));

TextView.setText(finalValue + " mm");

if your XMLdata.get("XMLField") is String convert it into float do the above method.

Answer 2

TextView.setText((Math.floor(MathXMLdata.get("XMLField") * 100.0) / 100.0).toString() + " mm");

This converts 10,5858555966668 to 1058,58555966668, rounds it to 1058 and converts it back to 10,58.

Note: Math.floor always rounds down (cuts off all missing fractional numbers). If you intend to round to the closest value, use Math.round.
