Signedness is a property of an integer number used by a compiler to indicate if variables of a numeric type are capable of storing both positive and negative numbers, or just positive. When performing arithmetic using a mixture of "signed" and "unsigned" variables, one might see an error such as: "pointer targets in assignment differ in signedness". The integers consist of the positive natural numbers (1, 2, 3, …), their negatives (−1, −2, −3, ...) and the number zero. ... A negative number is a number that is less than zero, such as −3. ...
