val number:Double = 0.0449999
val number3digits:Double = String.format("%.3f", number).toDouble()
val number2digits:Double = String.format("%.2f", number3digits).toDouble()
val solution:Double = String.format("%.1f", number2digits).toDouble()
//Or add extension
fun Double.shorten(decimals: Int): Double{ return String.format("%.$decimals" + "f", this).replace(',', '.').toDouble() } Source : https://stackoverflow.com/questions/49011924/round-double-to-1-decimal-place-kotlin-from-0-044999-to-0-1 | Last Update : Sun, 28 Feb 21
