is there a lib that'll do saturation math, or error / exception on overflow?
or do you just do it in
and check at the end?

I've actually been working on one, saturating and exact math should all work, with tests, but I'm not using it in any real projects yet so no guarantees (also has a multi-platform BigInteger and I'm planning a multi-platform BigDecimal, but there's some tricky cases I need to work through)
a bit complicated by codegen but the basic idea is simple
for error on overflow on JVM, there's standard Java methods
for Int-sized math, step up to Long
for Long, instead of using BigInteger you just have a variety of cases to handle based on sign
if you're only targeting JVM then Guava has all the exact/saturating arithmetic methods too

very cool. Yeah, I'm JVM only. And there are just a few times I want an error if I'm overflowing a long.
I have code for ULong but you probably don't need that
