The code I posted is not HexToDec, it's HexToAscii for a single nibble... I'm suprised Mihasic didn't notice that. To use it, you convert your 8 bit hex into 2 nibbles.

As far as I know there is no simple method for converting to decimal. I had a trick that worked if the number was 0-99. In that case the number would be prepped by dividing by 10, multiplying by 6, and added to the orginal number and sent through HexToAscii, avoiding one division by 10.

Bin2Ascii = HexToAscii((x/10)*6+x). Perhaps there is a better way to do this with DA too.

Hex(Bin) to Decimal has been discussed many times here. It involves dividing by 10 repeatedly.
