Give two double-typed variable X and Y.
If (X==Y) is true,
then how about the following results:
(float(X) > float(Y))?
(float(X) < float(Y))?
(float(X) >= float(Y))?
( X > float(Y) )?
( X < float(Y) )?

Should it be possible to create a custom class, 'Float', which would behave
as a drop-in replacement for the builtin float type?
As mentioned in another thread, I once tried this in rather a hurry to try
and catch some floating point naughtiness, but was stumped in various
places. Is there a fundamental obstacle to doing this?
thanks,
G.A.

float F=123.456000;
F*=1000; // Actually I used a for loop F*=10 three times.
printf("%f\n", F);
}
This will produce something like 123456.00XXXX, where XXXX are garbage
digits. Why is this happening, and how do I get rid of it? (using Dev-C++

Hi all:
I'm confused with the expression "(float *())".
Book says that this is a cast. But, I have no idea of this expr.
why could this expr ignore the variable???
Thanx!!!

Hi,
I have some software that does the following (in an attempt to determine
whether the double x, can be represented just as accurately by a float):
void test_it(double x) {
float y = x;
if(x == y) {
printf("x can be represented precisely by a float\n");
}

Hello,
I am having trouble implementing the following callback:
CNCSError CECWCompressor::WriteReadLine(UINT32 nNextLine, void
**ppInputArray)
where ppInputArray is a 3 by x array. The length of x is not known at
compile time.

Hi,
I have a doubt:
what is the difference between float **p and float *p?
Thanks in advance,

I have a 32 bit intel and 64 bit AMD machine. There is a rounding
error in the 8th digit. Unfortunately because of the algorithm we use,
the errors percolate into higher digits.
C++ code is

b += (float)(mode *val);
On 32 bit(intel , vs 2003, C++), some watch variables are

Folks,
We ran into a pretty significant performance penalty when casting floats.
We've identified a code workaround that we wanted to pass along but also was
wondering if others had experience with this and if there is a better
solution.

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...

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 particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
