Re: [U2] Another probably simple SB+ issue.
Jeff, What I did was while exiting from the session, there is a small SB+ dialog box that appears with 3 options, Close,New Session and Re-connect. Above those buttons, there is a check box which asks - Save session? I clicked that, and exited. When I logged back in, I found the check against Use Windows Print Drivers option chosen(whatever change I made). Can you please try and see if that works.

[U2] Any limitation in UniVerse decimal places
I shall explain the problem that I am encountering in the best detailed way that I can. I am working on a billing application (running on UniVerse), which sends details to a downstream application for invoicing. If several invoice groups are sent in one shot, where the total is approximately more that $20 million, an error occurs, due to rounding off. But when those invoice groups are sent one at a time, this condition does not occur. Is there any upper limit that is set in the configuration parameters? Can anyone please throw some light on this?

Re: [U2] Any limitation in UniVerse decimal places
(This response assumes that your upstream UniVerse billing application is totalling decimal amounts.) I don't know of specific limitations concerning decimal places, but I do know that precision differences in floating point math cause unexpected behavior. If you're trying to total dollar amounts in a program, it's a best practice to ICONV them into integers before any math operations -- this eliminates all floating point problems. AFAIK the query language RETRIEVE (i.e. LIST, SORT) performs math operations on the data as-stored in the record, then applies the OCONV before displaying the total (also avoiding floating point problems). rex apogee79 wrote: I shall explain the problem that I am encountering in the best detailed way that I can.

Re: [U2] Any limitation in UniVerse decimal places
Hi, In short, problem can be described as it is caused by? the fact that on certain condition represented by combination of large number of invoices and over 9 digits totals Universe engine creates a small fractional addition to total number. Not quite right. The problem here is that, just as there are numbers that cannot be represented accurately in decimal such as 1/3, there are numbers that cannot be represented accurately in the binary notiation used by the computer. As an easy example, the number 0.2 cannot be represented accurately and ends up as something like 0.20001 as a close approximation. Because IEEE floating point has a limited number of bits to store the matissa part of the value, the whole thing scales with bigger numbers. Essentially, a number cannot have lots of significant figures, wherever they may be in relation to the decimal point. If you add up a large number of figures with these rounding errors they may accumulate to something significant. Even worse, if you decide to do decimal scaling with a simple multiply instead of an MD conversion code, the inaccuracies get scaled too. This problem is not unique to UniVerse. It is a well known probelm of floating point numbers in computer systems. The usual fix in the multivalue world is to scale numbers (dollars to cents, for example) so that all our numbers are integers. UV also provides a set of character string arithmetic functions if you really want to get clever.

RE: [U2] Any limitation in UniVerse decimal places
Going way back to my pick days - I vaguely recall in some programs that used large number of digits to the left of decimal, we had to set the precision to a lower number (e.g. PRECISION 2). This basically took digits away from the right and made available to the left (assuming your data only has two decimal values).

Re: [U2] Any limitation in UniVerse decimal places
Hi, Th String maths routines (SDIV, SMULT etc) that Martin alludes to at the bottom of his post are very effective, but do require code changes to all the calcuations in the program. You can achieve the same effect in Universe by putting $OPTIONS STRING.MATH at the top of the program. However, there may be other reasons for getting rounding errors. For example, if you have a an invoice for a number of items and you wish to calculate the tax on that invoice, you can do this one of two ways. You can calculate and round the tax on each item and then add up the individual tax amounts. Or you can add up the value of the items and calculate and round the tax on the total value. The two methods can give different figures. I know most people in the list will be familiar with that scenario but sometimes it is worth making sure that the obvious issues are covered before looking for something more unusual. cheers, asvin The problem here is that, just as there are numbers that cannot be represented accurately in decimal such as 1/3, there are numbers that cannot be represented accurately in the binary notiation used by the computer.
