Code Review

This pull request replaces sge.convert with sql.literal when compiling comparison operations, and adds unit tests and snapshots to verify the handling of various float literals (such as infinity, NaN, and scientific notation). The review feedback correctly points out that using sql.literal will likely raise a NameError because the sql module is not imported, and suggests using sge.literal instead for consistency and safety.
