UInt16 Data Type

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

Instructions

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

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, the result is calculated as follows:

number Mod UInt16.Max + 1
Type changes
UInt16 widens to Int32, UInt32, Int, UInt, Int64, UInt64, Int128, UInt128, Real32, Real64, Real, or Real128 without risk of overflow.
Type characters
UInt16 has no type characters.

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 #fmt As Format) As UInt16
Tries to parse a string that shows as an integer.
If #fmt is not given or is #Null, then it tries to parse str as a decimal (base-10) integer. Or you can be explicit with Format.Base10.
UInt16.Size As Int
Returns the number of available bytes. This is always 2.

Examples

Example 1

Dim foo As UInt16

Example 2

Dim low As UInt16 = 0, high As UInt16 = 100
Dim result As UInt16 = low - high
After execution
VariableValue
low0 (&H0000)
high100 (&H0064)
result65436 (&HFF9C)
