hmm, it still requires floating-point support. It didn't work after #3209.

The application panicked (crashed).

This removed test was duplicated

The changes LGTM, but I think we better investigate and remove the usage of the floats (we can do it as a follow-up). I had a look and some usage comes from tendermint-rs and its use serde_json which should be easy to replace by serde_json_wasm
