kotlinlang

I'm trying to pack an `Int` as a `Short` in the upper part of a `Long`, but I get an out of range on declaring an hexadecimal number
```val l = (value.toLong() shl 48) and 0xffff_0000_0000_0000  // Error:(103, 42) Kotlin: The value is out of range. Expected: Long. Found: Int```
How can I solve? Casting to `Long` doesnt help

By the way, why do you need 0xFFFF mask here?

Just coherence, I need to pack others numbers in the same long in other positions

I mean, after shifting value 48 bits left, it seems to be useless zeroing these same 48 bits with the mask

I know, but as I said, for coherence and clarity

when I have to pack the next short on side, I do need to anding `0x0000_fffff_0000_0000`

I think it's an unsigned issue. Why not mask before you shift.

this did the trick `0xffff_0000_ffff_ffffUL.toLong()`
