Does anybody know why calling

toByte()

on

-128

results in

128

? Java bytes can only hold

-128

to

127

anyways! Example code:

fun main(args: Array<String>) {
    println(-128.toByte())
    println(-127.toByte())
}

Result:

128
-127

Casting

-128

to

byte

in Java returns

-128

as expected.

Interesting enough, factoring out the number to a local val fixes the issue:

fun main(args: Array<String>) {
    val v1 = -128
 	println(v1.toByte())
    val v2 = -127
 	println(v2.toByte())
}
