What is the full list of number suffixes in PowerShell?

问题

What is the full list of suffixes you can use on PowerShell number literals?
So far I have found:

╔════════╦═════════╦════════════════════════╗
║ Suffix ║ Example ║         Result         ║
╠════════╬═════════╬════════════════════════╣
║   L    ║   1L    ║ Type = Int64           ║
║   D    ║   1D    ║ Type = Decimal         ║
║   KB   ║   1KB   ║ 1KB = 1024             ║
║   MB   ║   1MB   ║ 1MB = 1048576          ║
║   GB   ║   1GB   ║ 1GB = 1073741824       ║
║   TB   ║   1TB   ║ 1TB = 1099511627776    ║
║   PB   ║   1PB   ║ 1PB = 1125899906842624 ║
╚════════╩═════════╩════════════════════════╝

But I can't find a source that would list all of them.

回答1:

According to the PowerShell Language Specification (V3) that is the complete set.

§2.3.5.1.1 Integer Literals includes: l, kb, mb, gb, tb, and pb.
§2.3.5.1.2 Real Literals adds d.

As far as I am aware (no update to the specification has been published) PowerShell V4 does not add any further suffixes.

The suffices are fully documented here.
