`UInt` Data Type

Holds unsigned integer values sure to be a minimum of 32 bits (4 bytes) and gives good 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, you find the result as follows:

number Mod UInt.Max + 1

Automatic conversions

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.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 #format As Format) As UInt: 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.
UInt.Size As Int: Returns the number of available bytes. Typical values are 4 or 8.

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 (%X00000000)`
`high`	`100 (%X00000064)`
`result`	`4294967196 (%XFFFFFF9C)`
