UInt Data Type

Holds unsigned integer values guarenteed to be at least 32 bits (4 bytes) and provides the best performance. On 32-bit platforms, values are in the range 0–4,294,967,295

Instructions

UInt is short for “unsigned integer”.

Default value

When you declare a variable of type UInt 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 UInt.Max + 1

Coercion

UInt widens to UInt64, UInt128, Real32, Real64, Real, or Real128 without risk of overflow.

Type characters

UInt has no type characters.

Shared methods and properties

UInt.Bits As Int: Returns the number of available bits. Typical values are 32 or 64.
uInt.Default As UInt: Returns the default value, 0.
UInt.Max As UInt: Returns the maximum value.
UInt.Min As UInt: Returns the minimum value. This is always zero (0).
UInt.Parse(str As String, Optional #fmt As Format) As UInt: 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”.

Examples

Example 1

Dim foo As UInt

Example 2

Dim low As UInt = 0, high As UInt = 100
Dim result As UInt = low - high

After execution
Variable	32-Bit Value
`low`	`0 (&H00000000)`
`high`	`100 (&H00000064)`
`result`	`4294967196 (&HFFFFFF9C)`
