Here's somewhat of an interesting problem. I am creating a class called
Rectangle. It takes in 4 sets of Cartesian coordinates (i.e. (x,y)
coordinates.). I'm assuming that the rectangle can be rotated too when
receiving these coordinates.
How would I go about setting methods to
A>"order" them (so that when i trace the outsides, point A,B,C,D all are
continous, as opposed to crossing in the "middle"...
B> testing that they are equal sides...

Hi All:
I'm a relative newbie to Python, apart from some CGI and shell scripting type
stuff. Anyway, I'm having some problems doing maths in Python 2.2.2 on RH9.
I'm wondering what is the best way or numerical data type to do simple monetary
calculations in Python? I only need to work with decimal numbers to two decimal
points. Are floating point numbers the only option? They're giving me hell!
If floating point numbers are the only...

Hello,
I've got a bit of experience in C++, but I'm writing my first app that
is dependent on relatively precise math functions. The app requires
that I get a time stamp based on s sample number, from a time series.
This seems liek an easy thing to do:
long lSample = 500; (for example)
double dSampleRate = 1000.0;

I have run an experiment to try to learn some things about floating point
performance in managed C++. I am using Visual Studio
2003. I was hoping to get a feel for whether or not it would make sense to
punch out from managed code to native code (I was using
IJW) in order to do some amount of floating point work and, if so, what that
certain amount of floating point work was
approximately.
To attempt to do this I made a program that...

I'm having a strange problem with a VB.NET App, and the built in
Windows.Forms.Datagrid
I have a tabbed interface, and a DataGrid (along with other controls) on
each of my two Tabs.
If the Datagrid on my first Tab has a horizontal scrollbar automatically
drawn because the table is too wide, and I switch to the other tab and
resize the form, when I switch back to the first tab, the horizontal
scrollbar on the datagrid is in the same...

Hi,
I'm relatively new with C-programming and even though I've read about
pointers and arrays many times, it's a topic that is a little confusing
to me - at least at this moment:
----
1) What's the difference between these 3 statements:
(i) memcpy(&b, &KoefD, n); // this works somewhere in my code

at least to me it is. I can't figure out for the life what it is i'm
doing wrong here.
i have a function called assign_coordinate. usually, i pass a malloced pointer
to it, then individual pointers are malloced within that function. No
problem here.
Now i have a situation in this software, where i need to assign new coordinates
to all nodes in the list.

Why is fmod(5.7, 0.1) = 0.1 ?? Why is it not 0?

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,...

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...
