Unsigned integers represent only non-negative integers and have a larger range of positive numbers than signed integers because the number of bits is the same for both representations. Refer to the Numeric Data Types Table for more information about numeric data type bits, digits, and range. There are four types of unsigned numbers.
| Byte (U8)—Byte unsigned integer numbers have 8 bits of storage. |
| Word (U16)—Word unsigned integer numbers have 16 bits of storage. |
| Long (U32)—Long unsigned integer numbers have 32 bits of storage. |
| Quad (U64)—Quad unsigned integer numbers have 64 bits of storage. |
