My immediate mission is to discover options for -as string. For example I have used:by Klaas at 2013-01-11 07:49:10
23.6969123 -as [Int]
My secondary question is how can I research the types for myself, thus apply the principle to other operators.

should give you all the possibilities
In your console you can typeGet-Help about_Type_operators

Is there any particular purpose you plan to use this operator for?
I checked Get-Help about_Type_operators, that revealed [DateTime], but I suspect there are more options.by DonJ at 2013-01-11 09:18:28
I just want to understand the boundaries of this operator.
The -as operator can attempt to cast/convert any object into another type. You can specify any .NET type name in square brackets, such as [System.Diagnostics.Process]. In practical terms, only simple objects usually support conversion, like converting a string to an integer or vice-versa. You can use full .NET type names, such as [System.String]. PowerShell usually lets you omit the "System." part, so [string], [int], [boolean], and so forth. There is not a comprehensive internal list of available short-type-names that you can access - the list you’re looking for doesn’t exist.by nohandle at 2013-01-11 09:20:21
Common ones include [single], [double], [int], [int32], [int64], [string], [float], [xml], [datetime], and so on. Some of those are technically type accelerators, like [xml]. But, again, there isn’t a way within the shell to retrieve a complete list of supported types, and the list has evolved through each version.
All of the objects inherit from the System.Object that opens the whole .NET for you :] The only restriction is that the source type can be ‘converted’ to the resulting type. The conversion is in my opinion using more like the parse static method of the class not casting. Because the resulting [datetime] follows the same rules as if you would do [datetime]::parse(‘13/1/2013’) not as if you would do [datetime]‘13/1/2013’ (obvious on non en-us systems :)).
