Java Double Currency Format to 3 Places -


this question has answer here:

i have java android app deals tips. when take in double of bill amount , tip percent, parse them to strings display later.

how can format doubles make currency more readable @ end? instead of looking $1.0 $1.00.

the code have mentioned is:

    final edittext amt = (edittext) findviewbyid(r.id.bill_amt);     final edittext tip = (edittext) findviewbyid(r.id.bill_percent);     final textview result = (textview) findviewbyid(r.id.res);     final textview total = (textview) findviewbyid(r.id.total);  double amount = double.parsedouble(amt.gettext().tostring()); double tip_per = double.parsedouble(tip.gettext().tostring()); double tip_cal = (amount * tip_per) / 100;  double totalcost = amount + tip_cal; result.settext("tip amount : " + " $ " + double.tostring(tip_cal)); total.settext("total cost: "  + " $ " + totalcost);

i result , total @ end outputs nicely formatted doubles 3 places. advice can give.

you can user decimalformat job you

ex

double x = 1.0; decimalformat decimalformat = new decimalformat("$#0.00"); string text = decimalformat.format(x);
