I want to use the digits from hex numbers as indices to a lookup table. Eg: if the number is A9, A corresponds to the row of the lookup table and 9 corresponds to the column, so that I can pick up the value of the cell at the intersection of this row and column.
How can I separate 'A' and '9' in hex?
