And didn't we go through this a while ago... Sqlite3's precision is 14...sometimes 15.... sqlite> select round(22.35-(5.45+16.9),15); 4.0e-15 sqlite> select round(22.35-(5.45+16.9),14); 0.0
So this also works: sqlite> select round(22.35 - (5.45 + 16.9),14), 22.35 = round((5.45 + 16.9),14), round((5.45 + 16.9) - 22.35,14); 0.0|1|0.0 -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Israel Lins Albuquerque Sent: Thursday, March 07, 2013 12:04 PM To: [email protected] Subject: [sqlite] Bug on real operations An example speaks more than words: Execute this: SELECT 22.35 - (5.45 + 16.9), 22.35 = (5.45 + 16.9), (5.45 + 16.9) - 22.35; The expected result on almost databases is: 0.0, true or 1, 0.0 But in sqlite for some reason they are: 3.5527136788005e-15, 0, -3.5527136788005e-15 I thing this can be a bug on calculation of doubles.
