Stylus: No implementation for floating point operation

[ImJeremyHe]

Describe the bug
Nitro: 3.12
I am writing our own stylus contract and running a nitro testnode for testing.

cargo stylus check -e http://localhost:8547 --wasm-file ./target/wasm32-unknown-unknown/release/espresso_crypto_helper.wasm --verbose

I got the error:

nitro-testnode-sequencer-1      | Caused by:
nitro-testnode-sequencer-1      |     No implementation for floating point operation ConvertIntOp(F64, I64, false) in user

It looks like our stylus contract is too compllicated to be deployed because it requires something unimplemented. I think the floating point operation has been implemented in the replay binary by using the soft-float wasm binary. Wondering if there is any solutions for us to call other WASMs or stylus contracts? Or maybe combine several WASMs into a single stylus contract? And if these operations are universal, can we support them in the stylus's native execution environment?

Expected behavior
cargo stylus check works

This is a known issue, floating point is currently not supported in Stylus. We are exploring different options, but nothing has been settled yet.
