   it's weird seeing people say floating point arithmetic is non-deterministic. it's actually very deterministic, to the pain of writing anything standard compliant

     @chjara@akko.wtf in theory, sure. but if you try to pretend that this is true in the real world then you will run into issues when someone tries to run your code on proper 32-bit x86 without sse2. or when you find out the hard way that sometimes AMD and Intel CPUs return slightly different results for a number of different transcendental operations

     @chjara i think people are confusing “imprecise” and “varies by processor architecture” with “non-deterministic”

     it’s entirely deterministic but it doesn’t give an exact result
