I have a few floating point questions/issues I wish to ask. An answer or
discussion would be nice too :) Any links discussion the subject would be
nice too..
1. How do I generate an underflow exception for testing purposes?
2. What is the fastest wat to suppress floating point exceptions?
Take the following situation as example.
float x = 1.0e38, //max float value

Does the C++ standard specify the behavior of floating point numbers during
"exceptional" (exceptional with respect to floating point numbers, not
exceptions) conditions?
For example:
double a = 1.0 / 0.0; // What is the value of a? Infinity?
double b = 0.0 / 0.0; // What is the value of b? NaN?
What about overflow/underflow conditions in the library? Is HUGE_VAL always a

Hi,
i´ve got an iteration with random generated floating point numbers.
During the iteration process sometimes the programm stops with the error:
"floating point error: overflow"
Is the number out of range? what does it exactly mean?
Thanks, Chris

I am having trouble with floating point addition because of the limited
accuracy of floating types. Consider e.g. x0 += f(n) where x0 and f are
of some floating type. Sometimes x0 is much larger than f(n) so that
x0 + f(n) == x0. For example, x0 could be 2**300*(1.1234...) while f(n)
is 2**100*(1.4256...). If x0 + f(n) == x0 I still sometimes want the
addition of f(n) to x0 to have some effect on x0. A good solution seems
to be to update...

<puts on Compiler Vendor hat>
I've recently discovered that our compilers don't
make any attempt to handle floating point overflow in add/subtract/
multiply/divide, with the result that programmers who don't range-
check their data can e.g. multiply two very tiny values and end up
with a very large one. This is (AFAICT) quite fine according to the
Standard but is certainly a QoI issue and I'd like to raise ours.
I believe that it's...

An article states: "In floating point maths, where if you divide by a
sufficiently large number sufficiently often, you will always be able to
reach a value too small to distinguish from zero, given the finite precision
you have."
What happens when "a value too small to distinguish from zero" is reached by
the above division? Underflow?
What does it mean "sufficiently often" since only one division should be
enough to cause underflow...

Does anyone have C code laying around to do this?
I have to read in some binary data files that contains some 4-byte
IBM/370 floating point values. I would like a function to convert
4-byte IBM/370 float values into IEEE 754 'float' values that I can
use directly with any modern C environment (that uses IEEE 754).
I can handle endian conversion myself (the files are stored as big
endian, and I'll process them on a little endian...

Hi people
I continue to work in the tutorial for lcc-win32, and started to try to
explain the floating point flags.
Here is the relevant part of the tutorial. Since it is a difficult part,
I would like your expert advise before I publish any serious nonsense.
Any comments are welcome, style, organization, hard errors, etc.

i have a program that i made in my class in Turbo C++ on windows 95or98 i belive. it is made to solve for factorials. th problem is that :
A) it puts it in exponents
B) theres too many numbers to count so i need a way to put commas every 3 digits and i dont know how to do that.
C) any factorials over 1754 give the computer an error that says:
Floating point: overflow
here is my program:
#include<iostream.h>

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,...

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....

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...
