Would BIGNUM work (assumes you are in 9.5 (64) ). For the report create
a BIGNUM variable just for the display.

Hey all,
I have a formatting problem that I don’t believe that I can use
formatting for.
The requirement is that the displayed number (in a report) can have no
more than 2 significant figures displayed.
Non-zero digits are always significant. Thus, 22 has two significant
digits, and 22.3 has three significant digits.
With zeroes, the situation is more complicated:
1. Zeroes placed before other digits are not significant; 0.046 has
two significant digits.
2. Zeroes placed between other digits are always significant; 4009 kg
has four significant digits.
3. Zeroes placed after other digits but behind a decimal point are
significant; 7.90 has three significant digits.
4. Zeroes at the end of a number are significant only if they are
behind a decimal point as in (c). Otherwise, it is impossible to
tell if they are significant. For example, in the number 8200, it
is not clear if the zeroes are significant or not. The number of
significant digits in 8200 is at least two, but could be three or
four. To avoid uncertainty, use scientific notation to place
significant zeroes behind a decimal point:
8.200 ´ 10^3 has four significant digits
8.20 ´ 10^3 has three significant digits
8.2 ´ 10^3 has two significant digits
So I believe that the best thing for me to do is to use scientific
notation.
The column definition I have been using in the report is a Double. I
cannot change the type but I know that this is a display issue.
However, my attempts to “force” scientific notation have not worked.
Any advice appreciated.
