Usage of float operators in the future WASM Actors implementation

[BlocksOnAChain]

Context: Good future question to resolve as we move closer to Wasm Acorst being on Mainnet - Will custom actors targeting Wasm be allowed to use float operators? We need to see if they will be "allowed", once WASM actors become available on Mainnet. Example from the industry - Cosmwasm, has some static analysis that blocks wasm contracts that contain float operators, which is a great feature to have.

Ah, that too, yes. E_TOO_MANY_ISSUES.

Including it then in the current MVP

Uhmm, yet wasmtime has canonicalization of floats, at least for NaN, https://docs.wasmtime.dev/api/wasmtime/struct.Config.html#method.cranelift_nan_canonicalization

[Stebalien]

Yes. That's the feature we plan on using.
