I am facing an issue where I need to do some calculations with a number like for example 5000,00 multiplied it by (1,025^3).
So in
Try val dec = DecimalFormat("#.###,00")
. For examples of DecimalFormat check this link.
Used:
%.numberf
fun main(args: Array<String>) {
var A: Double
A = readLine()!!.toDouble()
var bla = A*A
var calculator = 3.14159 * bla
println("A=%.4f".format(calculator))
}
val num = 1.34567
val df = DecimalFormat("#.##")
df.roundingMode = RoundingMode.CEILING
println(df.format(num))
When you run the program, the output will be: 1.34
Check: https://www.programiz.com/kotlin-programming/examples/round-number-decimal
This is the format you need:
val dec = DecimalFormat("#,###.##")
will print:
5.384,45
if you need always exactly 2 digits after the decimal point:
val dec = DecimalFormat("#,###.00")
