Was just catching up on the 1.3 announcement. I’m very excited about the unsigned ints stuff. I do a bit of protocol work. But I’m curious how they implement that on top of the JVM which does NOT have unsigned ints. Does anyone know? Are there performance implications?

There are no performance implications. Except for division but even that is minimal.

They're implemented with inline classes, so no overhead there, and I image a bunch of <https://www.hackersdelight.org/>

```internal fun uintDivide(v1: UInt, v2: UInt): UInt = (v1.toLong() / v2.toLong()).toUInt()```
damm that's lame.

It's cooler for longs though: <https://github.com/JetBrains/kotlin/blob/1d7ee22bdc2979dc20de7bcc364385ed283dc5d0/libraries/stdlib/unsigned/src/kotlin/UnsignedUtils.kt#L23>
