* Base contract that all upgradeable contracts should use.
* Contracts implementing this interface are all called using delegatecall from

* dispatcher contract, which allows the called contract to update these at will.
* _sizes is a map of function signatures to return value sizes. Due to EVM

How do I round to 2 decimals in python?

How do I round to 2 decimals?

All the examples use demical types, except for the original value, which is automatically casted as a float.

To set the context of what we are working with, let's start with an original value.
