Why Kotlin considers negative zero less than positive zero

Question

I was just starting to learn Kotlin, and I came across a strange suggestion in the documentation of the main types :

-0.0 is considered less than 0.0

I understand that their values ​​will not be the same in the supplement, but I do not know how this can be used in the code.
