I'm afraid I don't understand your problem. Decimal or hexadecimal are 
string representation formats, cardinal and integer values are stored 
and dealt with internally in binary form !
If your values are hexadecimal number stored in strings, why not convert 
them first to Cardinal ?

Could you perhaps give an example or be more precise ?
