integer division and modulo gives different results in c and python,
when negative numbers
are involved. take gdb as a widely available c interpreter
print -2 /3
0 for c, -1 for python.
more amazing, modulos of negative number give negative values! (in c).
from an algebraic point of view, python seems right, but I thought
python conformity to the underlying c compiler was a strong commitment,
obviously not here, and I found no...

In .NET, can I be sure that the result of a division between two integers
always is truncated rather that rounded to nearest?
Example:
99 / 50 = 1

Hi ppl,
I know it's forbidden to mention Java in this newsgroup but I've been
presented with a problem which requires that my C++ program
communicate with another java program.
What is the best,simplest and quickest way to go about this?
I was thinking, I could have my C++ program write data to a file and
then my Java program pick it up from there but this is a little too

hi,
i'm new to MS Visual Studio and C++ but not to C programming in general. i'm
trying to divide two integers and get their actual quotient (eg 5/3 =
1.666667 etc). i thought i had type cast correctly, but please let me know,
because it appears to be rounding off. my code follows. Thanks!
void DrawLine(GLint x1, GLint y1, GLint x2, GLint y2)

int i, pk, dy, dx, yc, xc, inc, temp;

Suppose that I have an integer division problem, but I want the answer was a
float. What's the cleanest syntax for that?
Example:
In this code, the variable z ends up == 0. And that is correct, because
this is integer division and the values are trunc'd. No problem. But
what's the most elegant code given that x and y have to be ints, and I want
z to be a float or double?
Code:

Hi,
The usually integer division will round the result to the biggest
integet smaller than the float version division.For example, 10/3 = 3.
I'm wondering if there is any easy way to round it to 4 for this case?
Thanks,
Peng

Hey, I have a project due around February 28. I have to create a program that asks the user for the number of players that want to play bingo. Then it creates that many bingo cards. Then it calls out BINGO numbers, but it can't make a repeat call out. Also, when something is called out, I have to somehow mark on the card that it has been called out. When the person gets 5 horizontally or vertically (not diagonally) then the programs says...

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
Here is the code in...

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,...
