Data Type

Used to store unsigned 32-bit integer values. The default value is 0. Generally you will use the Integer data type (equivalent to Int32 on 32-bit apps or Int64 on 64-bit apps) or UInteger (equivalent to UInt32 on 32-bit apps or UInt64 on 64-bit apps). This size-specific integer data type is available for use with external OS APIs.


UInt32 values can range from 0 to 4,294,967,295 and use 4 bytes.
