My problem is very simple but I am stuck with it: I Have a column called "Code". Let's say it is full of "3".

This column is the result of the reading of a memory encoded with 8-bit binary.

In my exemple, 3 is actually 00000011.

I would like to convert 3 into 00000011. I tried the script:

New Column**(** "**NEW_COLUMN**", Numeric, Continuous **)**;

**Column ( "NEW_COLUMN" ) <<Set Formula(**Char To Blob

But it fails. Any idea how to handle it?

Thanks in advance!

Jérôme

Hi Jérôme,

If you use the following formula, it will create the character string you want

base = Function**(** **{**n**}**,

{default local},

If**(** n != **0**,

ndash = "";

digits = "0123456789ABCDEF";

While**(** n > **0**,

remainder = Mod**(** n, **2** **)**;

newdigit = Substr**(** digits, **(****1** + remainder**)**, **1** **)**;

ndash = newdigit || ndash;

n = **(**n - remainder**)** / **2**;

);

ndash = Substr**(** "00000000", **1**, **8** - Length**(** ndash **)** **)** || ndash;

,

Ndash = "00000000"

);base**(**:Code**)**

**Assuming the target column is called "Code"**
