I'd like to convert a double to a binary representation. I can use the
"&" bit operation with a bit mask to convert *non* float types to binary
representations, but I can't use "&" on doubles.
To get around this limitation on double, I'd like to keep the bits of
the double the *same* but change its interpretation to long. I can use
"&" on longs. I tried to use reinterpret_cast for this purpose, but it
returned zero every time.

Hi there,
actually, I have posted the same question in g.g.help.
As there were no answers, I am still not sure whether this
is a bug or only something open to the compiler that is
seemingly inconsistent or whether my understanding of C
is not complete enough.
I would appreciate answers or pointers to answers very much.

Hi, All
I am reading FAQ of this group. I have a question about this:
http://www.eskimo.com/~scs/C-faq/q7.31.html
It says:
"
p = malloc(m * n);
memset(p, 0, m * n);
The zero fill is all-bits-zero, and does not therefore guarantee useful null
pointer values (see section 5 of this list) or floating-point zero values.

Hi,
I have something like this:
vector<floatvec1;
and I want to cast it, so I use
vector vec2<double= static_cast< vector<double(vec1);
I always become a

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

Let:
double x,y;
double z = max(x,y);
Does the standard ensure that
( z == 0.0 ) || ( x/z == 1.0 ) || ( y/z == 1.0 )
always gives true?

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...

Hello
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...
