I try to have all calculation and data-formation issues squared away
before applying display formatting. So, from R:SYNTAX, this might be
helpful:
(BRND(arg1,arg2,arg3))
Rounds REAL, DOUBLE, or CURRENCY data to a specific number of decimal
places and allows specification of the number of significant digits to
return. Arg1 is the value to be rounded. Arg2 is the number of
significant digits to return, and Arg3 is the precision. The precision
is specified as a decimal number, for example, .01 rounds to two decimal
places.
In the following example, the value of vresult is 1234.57.
SET VAR vresult = (BRND(1234.5678342,8,.01))
***
The datatype may then be easily redefined to suit your purpose, so that
display formatting is reliable child's play:
SET VAR vresult DOUBLE
SET VAR vresult TEXT
SET VAR vresult CURRENCY

Subject Re: [RBASE-L] - Where do I set my Vars?
Welcome to the not-so-wonderful world of the "REAL" datatype. Long ago
in DOS days that was the only datatype (other than currency) that
allowed decimals. Unfortunately it isn't real accurate IMO (pun
intended). Most of us switched all those Real numbers to the DOUBLE
datatype. With Double, a 104.31 is always stored and displayed exactly
as 104.31. With Real, internally that number may be stored as
something like 104.309187983. So depending on your display formatting,
you could get different representations to the screen.
Looks like the 000.## type of formatting might be truncating. In my
example, it would display as 104.30 or 104.309 even tho the number is
actually 104.31. Someone else suggested using the ROUND function if
you know how many decimal places you want displayed.

Hello Razzak,
Thank you - that is what I was looking for. I knew there was a simple
solution.
I am getting a strange output though: the real number stored is 104.31
000.## prints as 104.30
000.### prints as 104.309
This is an unusual situation where the number stored could possibly be
4 numbers to the left of the decimal and 3 to the right (we have never
had more than 2 to the right)
thanks for the help!

Lin,
Here's how ...
Please take a look at the attached illustration.
Open the report in Report Designer
Right-click on the Variable Object and select Display Format
Under the Display Format option change the Display Format to 0.000
Click on the [OK] button to save the Display Format
Click on the [Preview] Tab to preview while still in Report Designer
Save the report and close the Report Designer
That's all there is to it!
I hope it helps!
Very Best Regards,
Razzak

This will sound silly, but I am working on a system that I wrote
several years ago, but can't remember most of what I wrote!
I have a report that prints a Var (type: Real) It is now printing it
with 7 places after the decimal point. I need it to print a max of 3
places. Where do I set the number of places? I honestly can't
rmemeber!
