This isn't too hard.

For the first format, you'll want to bundle both hex values into a single one (normalize them) and process it like you would the second format. For the second format, it's very simple:

set hex "0x01f4"
set decimal [expr $hex]

or

 set hex "0x01f4"
scan $hex %x decimal

That would produce "500" as you want in $decimal.
