I assumed that it meant that if you ran code at compile time or at runtime, the results should be exactly the same given the same inputs.

And they believe Zig comptime wouldn’t do that? For the same inputs? I’d love an example.

		Traditional stuff in this space are: * floating point differences between the build machine and the target. By far the most common * endiannes - code assumes little median runs on big endian There’s other more subtle issues that can crop up but those are the big two.

		sin(x) can produce different results at comptime and runtime. In Rust there is no sin(x) at comptime for precisely this reason.
