Converting editable to double in Kotlin

Question

I have edit text in my layout. I want to get double and make some calculations on it. Due to it's editable I cannot make calculations and couldn't convert it to double.

Any easy way to convert it?

Answer 1

There would be !!.toDouble()

Try this:

fun main(args: Array<String>) {
var a = readLine()!!.toDouble()
var b = readLine()!!.toDouble()
println(a+b)
}
