Vista - [uint64] - [uint64] not defined

This blows:

352# $v = [uint64]54
353# $v | gtn
UInt64
354# $y = [uint64]454545454545
355# $y - $v
The operation '[System.UInt64] - [System.UInt64]' is not defined.
At line:1 char:5
+ $y - <<<< $v

I was trying to do some math on Win32_LogicalDisk (freespace and size).

$y + $v returns:

Cannot convert value "454545454545" to type "System.Int32". Error:
"Value was either too large or too small for an Int32."

Or limitation. Either way I think it should be fixed. Someone already
submitted this issue:

so I voted on it.

You can cast the (System.UInt64) WMI property into (System.Int64):
[long]$a = (gwmi win32_logicaldisk -filter "Name='c:'").size
