Hexdecimal digits, beyond the nineth element
Years and years ago, some bright ICT pioneer came to the conclusion that octal numbers were ideal for computer
engineering. He was right, in the days of the 12 bit ALU, but soon, the buswidths became multiples of 4 and 8
bits. And then grouping 3 bits together is not that obvious anymore.
So an even brighter (wo)man came to the conclusion that grouping 4 bits was even better and it took up less
digits. The problem, of course, was that the old Egyptians forgot to make 6 spare digits for this event. So,
the Bright Mind satisfied himself with the first 6 capital letters (A-F).
Bright it may have been, the problem is that now hexadecimal (another word for 4 bit groups, since 4 bits can
make up 16 digits) math became a lot more difficult since we didn't have proper names for the new postnine
digits.
Another reason to abandon the [A..F] semi-digit series is the problems met by programmers who need to display
these tokens on a 7 segment display. For the non-engineers: 7 segment displays are the digits of most digital
alarm clocks. You can make an 'A', but the 'B' looks like an '8' unless you go for the 'b', which looks like a
'6'.
This all is now to come to an end.
The
EUCET (European Union Computer Engineering Team)
have decided this official, Europe wide, nomenclature for the PostNine digits. The proposal is valid in the
European Union as of January 1, 2004 and all government agencies either have converted their documents
accordingly, or are in the process of doing so.
The same goes for the ICT engineers and programmers of government organisations. Commercial companies are
supposed to follow as of Februari 28, 2005.
EUCET
have organized a summit with BS and ANSI to come to a worldwide standard for the postnine digits. Rumour has
it, that President George W Bush has used his influence to convince the ANSI to meet the EUCET proposal. And
that's of course just how we got to know Mr President: a man of deeds.
EUCET hexadecimal digit proposal.
Below you will find a table with all the names and figures of the hexadecimal digits. Most of these are
pre-EUCET and The Committee have expressed they have no desire to change these. That would harm the
introduction of the postnine digits.

| Zero | Nul | Zero | Nul | 0 | |
| One | Eins | Un | Een | 1 | |
| Two | Zwei | Deux | Twee | 2 | |
