As you might imagine, an unsigned integer is either positive or zero. Given our discussion in the previous sections about binary numbers, it might seem that there is little more to say about unsigned integers.

At times, it is necessary to coerce an unsigned integer from one type to another, resulting in a change in the number of bits used to represent the number. When an unsigned integer is coerced from a larger length to a smaller length, high order (leftmost) bits are discarded.

Unsigned integers can be of all sizes, int, long, and short. The range of unsigned integers is through , where k is the number of bits, so for 16 bits the maximum unsigned integer is 65535. Unsigned integer constants are written using the suffix, u or U:

As a basic background for those of us who spend most of their time in T-SQL; an unsigned integer does not hold negative values. The value range is from 0 to the maximum of the datatype.
