Converting packed decimal to a char array

Hi all,

spend a lot of time and feeling like I run into a dead cycle with a
problem, that looks trivial.

I have packed decimals in my C programs that I need to convert to a
char array, representing the number (not zero terminated string).

For example:

decimal (15,9) A ;
char szTemp[32], sField[16] ;

sprintf(szTemp, "%016D(15,9)", A) ;
memcpy(sField, szTemp, 16) ;

What I want to achieve is get a function, that receives A and returns sField.
Of course it must support any types of decimal - not only decimal
(15,9) but others like decimal(11,7), decimal (15,0), decimal (5,0)
and so on. And, of course, decimal can be positive or negative...


Any ideas?

Jevgeni.
