Dominique, Thanks for that idea but now I have more questions?
So I decided to output 1000 digits, because why not? So now I am more perplexed with all these digits showing it is working the opposite of how I expected it. Why is the second set of equations evaluating to a "yes" when it is the only one that is obviously NOT equal to the expression??? SELECT printf('%4.1000f',9.2+7.9+0+4.0+2.6+1.3), case when (9.2+7.9+0+4.0+2.6+1.3)=25.0 then "yes" else "no" end, printf('%4.1000f',9.2+7.8+0+3.0+1.3+1.7), case when (9.2+7.8+0+3.0+1.3+1.7)=23.0 then "yes" else "no" end, printf('%4.1000f',9.2+7.9+0+1.0+1.3+1.6), case when (9.2+7.9+0+1.0+1.3+1.6)=21.0 then "yes" else "no" end Result 25.00000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000|no|22.999999999999990000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000|yes|21.00000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000|no -----Original Message----- From: sqlite-users-bounces at mailinglists.sqlite.org [mailto:sqlite-users-boun...@mailinglists.sqlite.org] On Behalf Of Dominique Devienne Sent: Friday, October 23, 2015 8:54 AM To: General Discussion of SQLite Database Subject: Re: [sqlite] Simple Math Question On Fri, Oct 23, 2015 at 3:45 PM, Rousselot, Richard A < Richard.A.Rousselot at centurylink.com> wrote: > Anyhow, one last question.

But instead, take control of the formatting, by using printf() from https://www.sqlite.org/lang_corefunc.html and use a format with more precision, and you should see the differences I think. --DD _______________________________________________ sqlite-users mailing list sqlite-users at mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users This communication is the property of CenturyLink and may contain confidential or privileged information.
