My knowledge of Solidity comes from reading the docs. It doesn't seem to support fixed point arithmetic either. The phrase "fixed point" appears in the ABI spec but nowhere else, shrug. Maybe half implemented? I guess you can implement it yourself as it does support bit shifts, assuming they aren't buggy too.

I pass no judgement on what belongs on Ethereum. I know from their website that they advertise it as a platform for general app programming and even implementing entire autonomous businesses. It clearly cannot support these things.

The Ethereum VM is not for general app programming. It's really not your typical environment. EVM contracts get executed on every network node, and it must return the same results everywhere.

We solved that for floats like 10 years ago. Let alone the fact there are better formats, like posits, or fixed point numbers, that also solve this problem very easily.
