I _really_ don't want to invent something here. When the setexpr thread came up before I went and did a little digging. Per https://en.wikipedia.org/wiki/Radix the general way to express a number is (x)y where x is the number and y is the base (and y is in base10, and also a subscript). I thought it was a bit cumbersome for general use and didn't bring it up at the time. If we're going to add some global way to always say a number is decimal, and I'm not sure I think that's a good idea even (I kind of think it might be better on a case by case basis to maybe tweak some prints so that for example "ls mmc 0:10" tells the user it's accessing partition 16 would lead to a quick "oh that's hex, #$%@!"), I think it should follow the radix notation, or if not, some other well known example. -- Tom
