How to declare an unsigned 32-bit integer?
The code from the currently accepted answer causes the following error on my system:
This is because PowerShell always tries to convert hex values to int first so even if you cast to uint64
, the environment will complain if the number has a negative int value. You can see this from the following example:
PS C:\> [uint64] (-1)
Cannot convert value "-1" to type "System.UInt64". Error: "Value was either too large or too small for a UInt64."
At line:1 char:26
+ Invoke-Expression $ENUS; [uint64] (-1)
+ ~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [], RuntimeException
+ FullyQualifiedErrorId : InvalidCastIConvertible
You need to cast the string representation of the number to uint64
to avoid this:
[uint64]"0xff000000" + [uint64]"0xAA"
0xff00000AA is too large for a 32 bit unsigned integer, use uint64
PS> [uint64]0xff00000AA

The simplest way is to cast to [uint32]
from a long
literal (with the L
suffix). You don't need to do the math in [uint64]
or cast from a string
[uint32]0xff000000L + 0xAA
In PowerShell 6.2 a series of new suffixes have been added including a u
suffix fof uint32
so this can be done even simpler
0xff000000u + 0xAA
