Compiler Rejects Floats (Defined twice?)

[Tellurian-Ul]

Possibly related to #566.

I'm unable to compile when floats are introduced to my code. I'm currently relying on nightly-2024-07-25 given the broken state of the compiler. I've posted the error I'm seeing upon cargo build below. My best guess is that the nightly override somehow created two definitions of floating point operations?

error: could not compile `project` (bin "project") due to 1 previous error

Does anyone know if there's a fix that allows floats?

Is this a duplicate of #541 maybe?

Looks like it. Probably safe to close this issue.
