number type without sign bit
In programming or math, describes a number type that can be zero or positive, but never negative.
Mẫu sử dụng:
[an] unsigned [int/integer/value/type]
Lỗi thường gặp:
Learners often think "unsigned" simply means "no plus or minus sign is written". In programming, it means the data type itself cannot store negative values because it does not use a bit to mark sign.
Từ đồng nghĩa
non-negative (General mathematical term; does not specifically imply a missing sign bit, but the range of values is similar.)
Từ trái nghĩa
signed (In computing, indicates a numeric type that can represent both negative and positive values using a sign bit.)
