UInt32 Data Type

Holds unsigned 32-bit (4-byte) integer values in the range 0–4,294,967,295.

Instructions

Default value
When you declare a variable of type UInt32 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 UInt32.Max + 1
Type changes
UInt32 widens to UInt, Int64, UInt64, Int128, UInt128, Real32, Real64, Real, or Real128 without risk of overflow.
Type characters
UInt32 has no type characters.

Shared methods and properties

uInt32.Default As UInt32
Returns the default value, 0.
UInt32.Max As UInt32
Returns the maximum positive value.
UInt32.Min As UInt32
Returns the minimum value. This is always zero (0)
UInt32.Parse(str As String, Optional #fmt As Format) As UInt32
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.
UInt32.Size As Int
Returns the number of available bytes. This is always 4.

Examples

Example 1

Dim foo As UInt32

Example 2

Dim low As UInt32 = 0, high As UInt32 = 100
Dim result As Uint32 = low - high
After execution
