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?

[Nikky]

if f is a UByte then you probably do not want to compare its value (which would be Byte)

[nestserau]

f.value is also UByte.

[nestserau]

f is my custom type.

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.

[hudsonb]

Ah yes sorry, you just need to do if (f.value.toUInt() in from..to && !c.isEmpty)

[hudsonb]

.. creates a UIntRange

Thank you Brian, that worked!
