I agree it's weird. I'm somewhat suspicious that it may be caused by the multiple merges. Some thoughts / questions: 1. Why would you expect the last 3 columns to...
One of the main difficulties here is determining the output precision. Many operations have different rules. This would likely need to be part of the type system, or allow arithmetic...
