This all seems ok on first glance, but now try to do some very basic math, such as addition and subtraction.
Quick what's 5|221 + 3|5?
Not intended for doing quick mental math... the intent is to shorten the representation on a web page and get the "order of magnitude" at a first glance.
When needed, it is very easy to convert to decimal. You do not need to count with your fingers the 5 zeroes on the web page (or was it 6?) to enter 5 zeroes on a calculator.
+1 and of course , those that wish to continue using scientific or good old 5 or 6 zeros 00000, keep doing that .
As I said it's easy to see the instance where it's just
z4 z5 z7 z8
Or
The good Drs
|5 |6 |3 |7
As this would represent
1z4 1z5 1z7 1z8
Or the like on the Drs method , ...
as when pricing something the nominal objective is to make a profit and the owner would likely just round up to the nearest 1 along the closest agreed market line.
