I am using Rekall which uses Python as it's scripting language and I have a question about Python. I am developing a POS system and am working on
the checkout form. I pass a parameter named SaleID and another one named Total. I am trying to take total and convert it to a float with 2 decimals top be used as money obviously. What would be the proper syntax for this? I tried Total = round(Total ) i also tried that with float.

Hi,
we found some strange behavior when operating with floats and round().
The following simplified statement reproduces the problem.
select 6.56 - round(convert(float, 6.56), 2)
from sysusers where name = 'public';

Hi everybody, I've got a problem.
I'm trying to round a double to a particular number of significant
digits, in this case 5, but I can't figure out a way around getting
_exactly_ what I want instead of _about_ what I want. Taken down to just
the part relevant to my question, here's the code, the desired result,
and the actual result...
double somenumber = round(2453126.7227083333 * 100000.0) / 100000.0;
desired: somenumber =...

How does one round a float? ie... 4.4 returns 4, while 4.5 returns 5.
I see the floor and ceiling functions, but that floor would take 4.4 and
return 4 and ceiling would return 5. I guess I could find the part after the
decimal, but there doesn't seem to be a way to do that either. Other then
subtracting the floor and multiplying by 10 and taking the floor of that and
checking if its 5 or higher, but that seems really lame. There has to...

No, not a question about "banker's rounding" or whatever it's called.
I want to round a double to the nearest 100th, so I perform the
following:
// original is a double
double result = Math.Round( original, 2 );
But I'm not happy with the results. E.g. if original is

It should be some simple way ...

Recently in our code, I ran into a situation where were stuffing a
float inside a double. The precision was extended automatically
because of that. To make a long story short, this caused problems
elsewhere in another part of the system where that figure was used for
some calculation and some eventual truncation led to the system going
haywire. So my question is, given this code:
int main()
{
float f = 59.89F;

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

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,...

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...
