Hi,
Does somebody have any idea about how to develop some VBA function or macro aiming conversion of several numerals types and that could be used for small and large numbers(e.g. 100000000000 in decimal)? The major numerals base for which I need this conversions a
Binary (Base 2)
Ternary (Base 3)
Quaternary (Base 4)
Quinary (Baase 5)
Senary (Base 6)
Septenary (Base 7)
Octal (Base 8)
Nonary (Base 9)
Decimal (Base 10)
Undecimal (Base 11)
Duodecimal (Base 12)
Base 13
Hexadecimal (Base 16)
Vigesimal (Base 20)

Thanks in advance,
Luciano

Hi there Luciano

Not sure if I am reading right or not.

Have a look at the following, it may point you in the right direction.

It assumes your numbers you want to convert are in Column "B", so
anytime you enter the base value you have presented the adjacent cell
will change its decimal count to the number entered.

I may have misinterpreted what it is you're needing, but someone else
may have another idea for you to run with.

Hey there Luciano

I do not respond to direct mail, unless invited.

The reason for this apart from Newsgroup Etiquette is that others whom
may have a similar need miss out.

I see you have a few responses to your other thread so will discontinue
this on.

Cheers
Mick.
