Seem to be some decimal coded binary, where you only use hexa from 0 to 
9, coding corresponding decimal digits.
The trailing hexa F may be used to indicate the end of the number (if 
number can have variable length) as it is normally not used as a digit 
in this coding.

Maybe... but have you an example of a negative number ?
