PowerShell doesn't understand unsigned numbers #3313
Description
Steps to reproduce
Description: I can't make powershell use correctly types like [uint32] or [uint64]. It seems like it always tries to dumb down every number to [int], and does it poorly. The bug seems to be that PS doesn't realize that is has to upcast 0xffffffff to int64 and not to int32, as it won't fit.
PS C:> [uint32]$b=0xffffffff
Cannot convert value "-1" to type "System.UInt32". Error: "Value was either too large or too small for a UInt32."
PS C:> $b=[uint32]0xffffffff
Cannot convert value "-1" to type "System.UInt32". Error: "Value was either too large or too small for a UInt32."
PS C:> $b=[uint64]0x1ffffffff
<so this works, because powershell realizes that 1ffffffff doesn't fit into 31 bit>
PS C:> $b=[uint64]0xffffffff
Cannot convert value "-1" to type "System.UInt64". Error: "Value was either too large or too small for a UInt64."
Expected behavior
PS C:\ > [uint32]$b = 0xffffffff
PS C:\ > $b
4294967295
Actual behavior
PS C:> [uint32]$b = 0xffffffff
Cannot convert value "-1" to type "System.UInt32". Error: "Value was either too large or too small for a UInt32."
