Adaptive Server 15.0 supports unsigned integer datatypes.
These unsigned integer datatypes allow you to extend the range of the positive numbers for the existing integer types without increasing the required storage size. That is, the signed versions of these datatypes extend both in the negative direction and the positive direction (for example, from -32 to +32). However, the unsigned versions extend only in the positive direction. This is the range for signed and unsigned datatypes:
