This code snippet by SkipVought is the best on the

http://www IMO.

Here is modifying it so you can optionally set the padding...

Function i2b(i, Optional p = 0)
   Do
      i2b = i Mod 2 & i2b
      i = Fix(i / 2)
   Loop Until i = 0
   i = Len(i2b)
   If i < p Then i2b = String(p - i, "0") & i2b

and going the other way...

Function b2d(b)
   n = InStr(1, b, "1")
   b = Mid(b, IIf(n = 0, 1, n))
   n = Len(b) - 1
   For c = 0 To n
      b2d = b2d + 2 ^ (n - c) * Mid(b, c + 1, 1)
   Next c
End Function

NOTE: Trims leading 0's

How time flies when yer havin' fun! And it was a fun exercise back, what, over a decade ago.

Well Gates & Co now have base conversion functions (decimal to binary, octal, hexadecimal and back), just without the Reverse feature, which was only there for that original poster's requirement. The functions are part of the MS360 suite of features in Excel, so I'm not sure they're accessible in Access.

There's also a DECIMAL() function that can convert a TEXT representation of a number in any base to decimal, where you supply the appropriate radix value.

And, as you'd expect, a BASE() function that converts a decimal to a value representation in any base such that 3 base 3 [BASE(3, 3)], would be represented as 10.

So, then, progress has caught us both and left us coughing in its dust trying to keep abreast.
