this is curious.. I have the following

infix operator fun <N> N.minus(other: N): N where N : Number, N : Comparable<N> =
        when {
            this is Byte && other is Byte -> this - other
            this is Short && other is Short -> this - other
            this is Int && other is Int -> this - other
//            this is Long && other is Long -> this - other
//            this is Float && other is Float -> this - other
            else -> error("Invalid operand types")
        } as N

Everything works fine, smart casting is kicking in properly.
However if I comment out one the last two lines, then it cast automatically the result to Any... ??

Not really #intellij.

[karelpeeters]

What two lines do you comment away exactly?

[elect]

what do you suggest?

[karelpeeters]

Just #general I guess.

[elect]

the ones that are commented right now

[karelpeeters]

Ah you're right, this might be #intellij

[elect]

😄

[karelpeeters]

Ah no it does make sense, - on Byte and Short returns an Int.

[elect]

?

[karelpeeters]

val x: Byte = ...
val y: Byte = ...
val r = x - y

[karelpeeters]

r has type Int.

[elect]

got it

[elect]

thanks

No problem. simple smile
