Hex Calculation

Hi

Does anyone have a calculation up their sleeve that will convert a numeric value into hexadecimal? I've tried myself with a combination of built-in functions, but I'm not very good at math so it never comes out right.

Thanks

Middle("0123456789ABCDEF",1+ Mod(Int(DecNum/16/16/16),16), 1) &

Middle("0123456789ABCDEF",1+ Mod(Int(DecNum/16/16),16), 1) &

Middle("0123456789ABCDEF",1+ Mod(Int(DecNum/16),16), 1) &

Middle("0123456789ABCDEF", 1+Mod(DecNum,16), 1)

... where DecNum is the decimal number you want to convert. This will handle up to 65535 decimal or FFFF hex. If you need more digits, just append more terms on the beginning of the calculation. Add an additional /16 for each one.

Thanks a lot. I'd got all the right functions, but couldn't get my punctuation right!

...BTW

How do I do it in reverse (hex to dec)?

(((Position("0123456789ABCDEF", Upper(Middle(HexNum, 1, 1)), 1, 1)-1)*16+

Position("0123456789ABCDEF", Upper(Middle(HexNum, 2, 1)), 1, 1)-1)*16+

Position("0123456789ABCDEF", Upper(Middle(HexNum, 3, 1)), 1, 1)-1)*16+

Position("0123456789ABCDEF", Upper(Middle(HexNum, 4, 1)), 1, 1)-1
