is there a nice way to have an overloaded function that accepts all (nullable) unsigned types, and to call that function with

0u

? At the moment Kotlin doesn’t know which unsigned type to use, and errors with

Overload resolution ambiguity

.

It appears to be an issue (https://youtrack.jetbrains.com/issue/KT-46360) that has been present for some time.

0u.javaClass.typeName

outputs

kotlin.UInt

, yet it still prints this error on

operation(0u)

. You can use parameter names like you did with

operation(uLong = 0u)

, but you can also call one of the "casting" methods, such as

operation(0u.toUInt())

,

operation(0u.toUShort())

, etc. As for a generic method matching all unsingned types, I'm not sure how. Looking at the API, it doesn't seem like they extend any other types like

Number

, they only implement

Comparable<T>

.

thanks for finding that issue @Laertes Moustakas I’ve made an additional issue https://youtrack.jetbrains.com/issue/KT-55999
