About usage of floating point in the oracle script

[zicofish]

Hi, while reading the documentation, I found the usage of f64 in the following oracle script example:

https://docs.bandchain.org/core-concepts/oracle-webassembly

You mentioned that your script is run on-chain instead of off-chain, but Cosmos cosmwasm doesn't support floating points because they are not safe. So I was wondering what's the trick with Owasm? Is the script really run on chain, or there might be misunderstanding of concepts from my side?
