How can i show the value before the "." sign?

Issue

I'm creating a currency application but some of values are like "194.23564" or "1187.7594" so i want to show the user before the "." sign values. How can i make this with Kotlin ?

Solution

There is no need for data type conversion before the extraction of the integer part.
You can use substringBefore():

val number = "194.23564"
val intPart = number.substringBefore(".")

If you want the result as an integer number you can use now toIntOrNull(), instead of toInt(), so to avoid an exception in case the initial string has no integer part (like ".015"):

val intPart = number.substringBefore(".").toIntOrNull()
