😵‍💫

APIs 24 and 25 are producing weird values for Longs close to MAX_VALUE. I wonder if there was a bug in those old versions of ICU.

If it's deterministic I would put a

val expected = if (SDK_INT in 24..25) {
  // Some comment...
  "12345579$828#838828@"
} else {
  "82837447736161616474"
}
assert...

I bet that's the 64-bit max represented as a Double. Once you exceed the 53-bit precision you start jumping numbers and so it would lose 10 bits of precision for that number.
