Decimal point issue in displaying digits

I have to display digit in two decimal points.

Let say value 0 should display as 0.00 and value 2.3 shoule display as 2.30.

To achive this I have done something like below :

Log.e(">>> percent ", ">> " + data.percent)
percent = String.format("%.2f", percent).toDouble()
Log.e(">>> percent ", ">> " + percent)

But the result you will notice is as below :

2021-04-15 11:55:54.580 10061-15047/com.dev E/>>> percent: >> 0
2021-04-15 11:55:54.580 10061-15047/com.dev E/>>> percent: >> 0.0

It should be 0.00 instead of 0.0

What might be the issue? Please guide. Thanks.

String.format("%.2f", percent).toDouble()

to

String.format("%.02f", data.percent)

You can use DecimalFormat https://docs.oracle.com/javase/7/docs/api/java/text/DecimalFormat.html

val df = DecimalFormat("0.00")

df.format(percent)

Double type does not have information about how to display.

So, do not use toDouble() method to the string. Also, add 0 to the format string to denote the zero padding.

Log.e(">>> percent ", ">> " + data.percent)
val percentStr: String = String.format("%.02f", data.percent)
Log.e(">>> percent ", ">> " + percentStr)
