UInt16 Data Type

Holds unsigned 16-bit (2-byte) integer values in the range 0–65535.


Default value
When you declare a variable of type UInt16 and do not initialize it, its default value is zero (0).

If you use the negation operator (-) on an unsigned type, ViviFire gives a warning that this operation is usually an error.

If you subtract a larger number from a smaller number, you find the result as follows:

number Mod UInt16.Max + 1
Automatic conversions
UInt16 widens to Int32, UInt32, Int64, UInt64, Int128, UInt128, Real32, Real64, or Real128 without risk of overflow.
Type characters
You can put the suffix u16 (or U16) on the end of an integer literal. But there are no type characters for names.

Shared methods and properties

UInt16.Default As UInt16
Returns the default value, 0.
UInt16.Max As UInt16
Returns the maximum positive value.
UInt16.Min As UInt16
Returns the minimum value. This is always zero (0)
UInt16.Parse(str As String, Optional #format As Format) As UInt16
Tries to parse a string that shows as an integer.
If #format is not given or is #Null, it tries to parse str as a decimal (base-10) integer. Or you can make it clear with Format.Base10.
UInt16.Size As Int32
Returns the number of available bytes. This is always 2.


Example 1

Dim foo As UInt16

Example 2

Dim low As UInt16 = 0, high As UInt16 = 100
Dim result As UInt16 = low - high
After run
low0 (%X0000)
high100 (%X0064)
result65436 (%XFF9C)
