Hi everybody.

When I try:

select (2183.48/(1-(37.25/100))) as valor from rdb$database

As result  Firebird: 3465,8412

But other databases(MSSQL) and spreadshets(Excel and Calc) the correct result is 3479,6494023904

If I change  (37.25/100) to 0.3725 as follow:

select (2183.48/(1-0.3725)) as valor from rdb$database

Then Result is correct 3479,6494023904

I would like to understand why this

or if it´s a new bug to post.

Firebird-2.5.4.26856_0_Win32

No, I don't think this is a bug. If you do

select 37.25/100 as valor from rdb$database

the result is 0.37, not 0.3725. To fix your original problem (well, it will be rounded to 4 digits after the decimal point, just add zeroes (or cast):

select (2183.48/(1-(37.2500/100))) as valor from rdb$database

HTH,
