Simply because the edge cases for working with e.g. '0xC.68p+2' in a hypothetical future Python are less obvious and less simple to demonstrate, I feel like learners will be tempted to think that using this base-2/16 representation saves them all their approximation issues and their need still to use isclose() or friends.
