Floating Point with 2 Digits after Point
You can also use DecimalFormat
float f = 102.236569f; DecimalFormat decimalFormat = new DecimalFormat("#.##");float twoDigitsF = Float.valueOf(decimalFormat.format(f)); // output is 102.24//double twoDigitsF = Double.valueOf(decimalFormat.format(f)); also format double value
In answer above it always will return 2 deciaml
examples with String.format("%.02f", f)
2.5555 -> 2.55
2.5 -> 2.50
but do you need to get 2.50 for 2.5?
for avoid to get excessive 0, you can use this solution
val format = DecimalFormat("0.##")return format.format(floatNum)
