UInt8 Data Type

Holds unsigned 8-bit (1-byte) integer values in the range 0–255.


Default value
When you declare a variable of type UInt8 and leave it uninitialized,, its value defaults to zero (0).
Because UInt8 is an unsigned type, when you use the unary minus (-) operator on an expression of this type, the value is first changed to Int16 then negated.
The UInt8 data type widens to Int16, UInt16, Int, Uint, Int32, UInt32, Int64, UInt64, Int128, UInt128, Real32, Real64, Real, or Real128 without any risk of overflow.
Type characters
UInt8 has no type characters.

Shared methods and properties

UInt8.Bits As UInt
Returns the number of available bits. This is always 8.
UInt8.Max As UInt8
Returns the maximum positive value.
UInt8.Min As UInt8
Returns the minimum value. This is always zero (0)


Dim foo As UInt8
