The following code throws an error that == cannot be applied between int and short.
if(shortVal == 3)
Does Kotlin have a way to denote that a numeric literal is a short, something like 3S?
There is no functionality like that in the standard library, as far as I know. But you're still free to implement a functionality like that on your own, e.g. using Kotlin's extension properties.
val Int.s: Short
get() = toShort()
val i: Int = 3
val s: Short = 3.s
You could also create an infix function instead of ==.
I called it eq
infix fun Short.eq(i: Int): Boolean = this == i.toShort()
And you can use it like this
if(shortVal eq 3)
