- Using unsigned integers is often more appropriate because most integers in programs do not represent negative values.
- Common arguments against unsigned integers, such as safety and reverse loops, are addressed with correct idioms that avoid underflow issues.
- Unsigned integers allow safer calculations for differences, midpoint computations, and overflow checks compared to signed integers.
- The default use of signed integers in languages like C and C++ is a legacy choice, and unsigned can simplify code and improve diagnostics.
- Languages with defined wrap for signed integers still face safety issues, and unsigned integers force consideration of all input ranges.
