fun <T : Comparable<*>> compareValues(a: T?, b: T?): Int
(source)

Compares two nullable Comparable values. Null is considered less than any value.

import kotlin.test.*

fun main(args: Array<String>) {
//sampleStart
println("compareValues(null, 1) < 0 is ${compareValues(null, 1) < 0}") // true
println("compareValues(1, 2) < 0 is ${compareValues(1, 2) < 0}") // true
println("compareValues(2, 1) > 0 is ${compareValues(2, 1) > 0}") // true
println("compareValues(1, 1) == 0 is ${compareValues(1, 1) == 0}") // true
//sampleEnd
