Entering 3.4 in Python yields 3.3999999999999999.
I know it is due to the fact that 3.4 can not be precisely expressed by the
powers of 2. Can the float handling rules of the underlying layers be set
from Python so that 3.4 yield 3.4?
Thanks,
Károly

I did it.
I proposed python as the main language for our next CAD/CAM
software because I think that it has all the potential needed
for it. I'm not sure yet if the decision will get through, but
something I'll need in this case is some experience-based set
of rules about how to use python in this context.
For example... is defining readonly attributes in classes
worth the hassle ? Does duck-typing scale well in complex

I'm using DB2 UDB 8.1.2 on Suse linux. Try this:
CREATE TABLE testsums (cost_of_sale decimal(7,2), price decimal(9,
2));
INSERT INTO testsums VALUES (10000, 30000);
SELECT cost_of_sale/price AS division1 FROM testsums;
SELECT sum(cost_of_sale)/sum(price) AS division2 FROM testsums;
The first select gives 0.333333333333333333333333
The second gives 0.

Hello
Could anyone tell me how to send a null decimal value to the sql
server depending on its value?
The following code gives me an error:
System.Data.SqlTypes.SqlNullValueException: Data is Null. This method
or property cannot be called on Null values.
I figured out SqlDecimal.Null is used only with db Money fields. But
when I changed SqlDecimal.Null to DBNull.Value I got the error:
CS0173 Type of conditional expression can't be...

How in the hell does one specify the precision and scale for the
SQLDecimal type? I am writing a user defined CLR SQL Server function
and one of the function parameters is a decimal value which in SQL
Server would be type numeric(18,6), but the only type that seems to be
an equivalent on the VB 2005 side is SQLDecimal, but there seems no way
to set the precision and scale for this (outside of using a new
constructor, which is not allowed...

Hi,
I would like to be able to read the scale & precision of a decimal type
contained in a sql server table from vb.net.
I would like to set some properties (like width,format) of a gridview's
field based upon the width (scale,precision) of the database column.
Previously, in VB6 with ADO i was able to do that.
In .Net i can read the dataType, but that returns me a .net decimal and
apparently i cannot read a scale/precision from that.

Hi,
I have a column defined as decimal(4,3).
I get the following error when I try to insert "12.50000000000000"
CLI0111E Numeric value out of range. SQLSTATE=22003
sqlstate = 22003
I even tried with "12.500" and "12.50" , but still get the same error.
My point here is, it allows only one number before the decimal point.

This one cost me a solid half hour yesterday. I'm wondering why on
earth the default precision for a decimal type is 18,0. Maybe I'm
mistaken. A decimal datatype sort of implies that you'd want something
after the decimal!
Question is, can I set this database-wide? Like all new decimal
datatypes have a precision of 12,6 or something like that? I haven't
seen anything about this in the googling I have done...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
