Guys, the IDE asks me to convert the comparison of `UByte`s into a range check. And I would gladly do it, but if I do

if (f.value in from..to && !c.isEmpty)

, then it doesn’t compile saying

Type interference failed

. Any other options?

fun notEmptyFieldInRange(from: UByte, to: UByte): Boolean {
        for ((f, c) in fields)
            if (f.value >= from && f.value <= to && !c.isEmpty)
                return true
        return false
    }

What's `f.value`s type?

if

f

is a UByte then you probably do not want to compare its

value

(which would be

Byte

)

f.value

is also

UByte

.

The following snippet works fine. I'd verify

f.value

is a

UByte

as you believe.

val f = 5u
val from = 0u
val to = 10u
if(f in from..to)
    println("works")

In your example all values are

UInt

. That will work indeed. Not in case of

UByte

.

f.value

is really

UByte

, doublechecked that.

Ah yes sorry, you just need to do

if (f.value.toUInt() in from..to && !c.isEmpty)

Thank you Brian, that worked!
