Does anyone know why you can't use

0x800...

in Kotlin? With the below, I get an error:

Copy code

fun readTopmostBitFromLong(value: Long): Boolean {
    return value and 0x8000000000000000L != 0L

one workaround:

0x8000000000000000UL.toLong()

in this case you can simply replace the function with

value < 0

though
