Description:
------------
When SQL query returns numbers with precision 7, 8 or 12-14 (digits after period) ibase_fetch_*() returns these numbers divided by 10. 
When precision are 18 - returns "29".
I was tested this on PHP 5.2, 5.1.6; on WinXP and RedHat Linux; on Firebird 1.5 and 2.
Maybe, this is some bug with #39056 ?

Reproduce code:
---------------
//generate SQL
$nums=array();
for($i=0;$i<=18;$i++) {
	$nums[]=sprintf('1.%s AS prc_%d', str_repeat('0',$i), $i);
}
$stmt='SELECT '. implode(', ',$nums). ' FROM RDB$DATABASE';

//query
$dbh = ibase_connect('localhost:c:/main.gdb', 'SYSDBA', 'masterkey');

$sth = ibase_query($dbh, $stmt) or die(ibase_errmsg());
$res=ibase_fetch_assoc($sth);
   
print_r($res);


Expected result:
----------------
PHP 4 outputs:
Array
(
    [PRC_0] => 1
    [PRC_1] => 1.0
    [PRC_2] => 1.00
    [PRC_3] => 1.000
    [PRC_4] => 1.0000
    [PRC_5] => 1.00000

    [PRC_10] => 1.0000000000
    [PRC_11] => 1.00000000000
    [PRC_12] => 1.000000000000
    [PRC_13] => 1.0000000000000

Actual result:

You can try to change the lines mentioned in #39056 (see ext/interbase/ibase_query.c) and tell us if it works.
I don't think anybody here uses Interbase these days.

Take the solution from #39056, add two strings to them (for precisions 17 and 18) and .... it works! :)

I think, same error is present in function firebird_stmt_get_col() from ext/pdo_firebird/firebird_statement.c .

Are the php_interbase maintained?
Please, fix this bug before PHP-5.2.1. Just recount the nulls in "scales" array :)

>Are the php_interbase maintained?
No, feel free to take it over.
