Similar to this issue, nan:0x200000 and -nan:0x200000 cannot be parsed, and the same error message "invalid float literal" is reported.

In addition, -nan is parsed into nan, which is incorrect. nan and-nan represent different meanings, and their bits are different.

Yes this is expected as the CLI uses the Rust standard libray to parse floats right now, which is not the same as the text format of WebAssembly.

Is that going to fix the problem?

Sorry I'm not sure if I understand your question?

To clarify what I'm saying, the parsing of f32/f64 in the CLI isn't specified right now in Wasmtime and it's "whatever rust libstd happens to implement". The syntax you're describing here I think is probably coming from the text format of WebAssembly, however, which isn't plumbed into this part of Wasmtime right now. Assuming you want the same text format of WebAssembly then yes I believe that will resolve this issue.

Yes brother, I shouldn't describe it as a problem, this format is from webAssembly. It would be great if wasmtime should support this format in the future.
