Let’s take a look at what is being asked here. Using the 32-bit integer as an example, we currently have a data type that can accept a range between negative two billion and two billion. But if negative numbers aren’t required, we can use those same 32 bits to store numbers between zero and four billion. Why, goes the question, throw away that perfectly useful upper range by always reserving space for a negative range we may not need?
I appreciate Ewald’s thoughtfulness here in working out the value of the request as well as some of the difficulties in building something which fulfills his desire. Great read.
