Open the query and have a look. Says all.
Open the attaches Firebird 3 database.
Open the query.
I tried to divide an Integer with 2:
1/2 = 0
This shows, as expected, wrong values, because there isn't defined a decimal-point.
So I tried Integer/2.0 , which works in HSQLDB.
Firebird divides with 2 and multiplicates the result with 10.
1/2.0 = 5
So I thought: Might be Firebird doesn't know how to handle the decimal point. Will try it with Decimal and a value with 2 digits.
1.00/2 = 50
Seems Firebird ignores the digits of the Decimal and works with 100 instead of 1.00. So I tried again with Decimal 2 digits and divide through 2.0
1.00/2.0 = 500
Tried all this with

script for isql-fb for comparison
Just in case there was any doubt, the problem is LibreOffice. isql-fb
returns the expected results (abbreviating long column names in the
obvious way) ...
ID Int Int/2 Int/2.0 D2D D2D/2 D2D/2.0

1 1 0 0.5 1.00 0.50 0.500
2 2 1 1.0 2.00 1.00 1.000

It feels like a confusion between "." as thousand separator and decimal point.
It also happens in Tools/SQL.
Have tested this a little bit more:
SELECT CAST("Integer" AS FLOAT)/ 2.0 "Integer/2.0_Float", CAST ("Decimal_2_Digit" AS FLOAT)/2.0 "Decimal_2_Digit/2.0_Float" FROM "Table"
gives the right value for both. The decimal point works right with Float (or Double Precision), but doesn't work with Decimal (or Numeric). If I set
CAST("Integer" AS NUMERIC)/ 2.0
the result is as wrong as described in bug-report.
I will set this bug to version 184.108.40.206alpha0+, because the buggy behavior is introduced with Firebird 3.0.
It turns out that for computed numeric/decimal values firebird does not set subtype to either numeric or decimal.
In isql and jaybird (jdbc driver for firebird) the problem is solved by checking not only for subtype but scale of the column too. So I decided to do the same in this patch:
Tamás Bunth committed a patch related to this issue.
It has been pushed to "master":
tdf#105101 check scale to determine subtype
It will be available in 5.4.0.
The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More

Affected users are encouraged to test the fix and report feedback.
Works now, also for other numeric functions.
Could this be backported to LO 5.3.1?
Eminently composed article, if just all bloggers offered the same substance as you, the web would be a far superior spot. https://enjoy-the-life-baby.com
I love the blog. Great post. It is very true, people must learn how to learn before they can learn. lol i know it sounds funny but its very true. https://www.singinglikepro.com

A great blog that I recommend to all my friends! I do not even know what I did without your advice, great work! https://small-home-ideas.com
Superbly written article, if only all bloggers offered the same content as you, the internet would be a far better place. https://www.debt-to-income.com
The primary thing you'll have to do is begin composing as quickly as time permits. Numerous understudies don't do this, as they feel it's an exercise in futility. All things considered, on the off chance that you begin composing before you've gone out and done the exploration, at that point, it might all not be right and you'll need to discard it.
Contents for TV or theater are never going to mirror the manner in which individuals really talk: common discourse is excessively loaded with falterings, errors, and arbitrary deviations to be fascinating in an emotional setting. Nonetheless, it's additionally conceivable to go excessively far the other way. At the point when your characters need to pass on significant snippets of data to one another, it's anything but difficult to fall into the snare of having them pose each other inquiries and offer the responses straight away.
Works now, additionally for other numeric capacities.
Looks like you mistakenly reopened the bug. Closing again.
