Decimal to Hexadecimal
 

So, my company tracks items based on DEC and HEX, some with one, some with
the other. I'm tryign to create a formula that will convert items that have,
say DEC to HEX and vice versa. Problem is, when I attempt DECTOHEC and
HEXTODEC, it doesn't match what I get using my company's lookup tool (an
arduous process)

Here's what the company conversion are for a sample set of numbers:
DEC HEX
02313552326 17cecac6
02313552451 17cecb43
02313552469 17cecb55
02313552512 17cecb80
02313552538 17cecb9a
02313552779 17cecc8b
02313552798 17cecc9e
02313552829 17ceccbd
02313552891 17ceccfb
02313552900 17cecd04
05112837432 33C3E238

And Dec2Hex() gives me:
DEC HEX
02313552326 89E601C6
02313552451 89E60243
02313552469 89E60255
02313552512 89E60280
02313552538 89E6029A
02313552779 89E6038B
02313552798 89E6039E
02313552829 89E603BD
02313552891 89E603FB
02313552900 89E60404
05112837432 130BFB538

I'm missing something... :-/

Sean,

Your Co conversions look dodgy to me and the results Excel comes up with
can be verified here http://www.statman.info/conversions/hexadecimal.html.

The Excel values seem correct to me, two different calculators
and the Windows calculator!

Yes: the fact that your company uses a special algorithm to effect the
conversion, not a straigtht-forward conversion from decimal to hex,
like Excel does.

Here's what the company conversion are for a sample set of numbers:
DEC HEX
02313552326 17cecac6
[....]
05112837432 33C3E238

I might not be able to tell you the precise algorithm. But based on
the few examples given, the following Excel formulation yields the same
results:

=DEC2HEX(LEFT(A1,LEN(A1)-8)) & DEC2HEX(RIGHT(A1,8))

where A1 is the decimal number. In other words, the right-most 8
digits are taken as a number and converted to hex, which is appended to
the remaining left-most digits taken as a number and converted to hex.

Hi. Your company breaks the Dec number into 2 parts.
23 & 13552326

23 is 17 hex
13552326 is cecac6 hex

Now, that was some good calculating! thank you su much for figuring that out!
It was driving me silly!

=DEC2HEX(LEFT(A1,LEN(A1)-8)) & DEC2HEX(RIGHT(A1,8))

That works fine when the right-most 8 digits form the number 001048576
or higher. That always yields 6 hex digits. It is unclear what your
company's algorithm would do with "numbers" less than 001048576. If
they zero-fill to 6 hex digits, as I suspect, use:

=DEC2HEX(LEFT(A1,LEN(A1)-8)) & DEC2HEX(RIGHT(A1,8),6)

Also note that the formula assumes the entire decimal number (A1) is at
least 9 digits.
