I was hoping for the generic solution to the performing modulus against a ULARGE_INTEGER (and even LARGE_INTEGER), in a compiler without native 64-bit support. That would be the correct, good, perfect, and ideal answer, which other people will be able to use when they need.
I was carrying out a calculation in raster calculator in ArcMap 10.4 where I multiplied two rasters together. Both rasters had the same extent, were snapped to each other and have the same pixels overlapping. When using the identify tool, I noticed that the result was different to if I worked it out myself. For example, the calculation for a particular pixel was 37.572238*90428390 (so should equal 3,397,596,991.03682). However the actual result from the raster calculator equaled 3,397,596,987.419. I also carried this out in QGIS to test and got another different result of 3,397,596,928.000.
Most scientific and graphing calculators can only display possibly up to 10 decimal places of accuracy. While this is enough in most instances of everyday use, it can be fairly limiting for applications where higher standards of accuracy are necessary. Hence the existence of big number calculators such as the one above, that can provide far higher levels of accuracy. Big numbers are more likely to be used in fields such as cosmology, astronomy, mathematics, cryptography, and statistical mechanics.
In some cases, the numbers worked with are so large that special notations such as Knuth's up-arrow notation, the Conway chained arrow notation, and Steinhaus-Moser notation were conceived. Nevertheless, there are certainly scientific uses for big number calculators today, and even if a person may not have any need to use one, it can certainly be entertaining to sate one's curiosity of what 10,000 factorial looks like on a screen. Below is a table that shows big numbers in terms of powers of 10 as well as their respective names.
I was just wondering why the Windows calculator that comes with the LTSC-version of Windows (which actually is the old classic calculator from Windows 7, because the LTSC version does not come with the new modern UI calculator installed) is producting wrong results, or crashes when switched to "Programmer mode".
I have recently been struggling to make my program faster because it has been spending a long time to get a result. So for speed-up, I have parallelized the most time-consuming part using OpenMP. This worked very well and gave a nice speedup. Now I am considering the use of single precision (32-bit) for the time-consuming part, because my program is written entirely in double precision (64-bit). So, I am wondering whether there are some remarks that I should keep in mind for this kind of calculations.
More generally, although I have used only 64-bit up to now, is it rather common to perform an entire calculation in 32-bit? I think neural-net calculations use lower-precisions for speed-up, but wondering what kind of other applications typically use 32-bit (partly or entirely). I think this depends greatly on the nature of calculations (whether the calculation is deterministic and needs high precision, or it is stochastic and inherently subject to random noise).
Depends on whether you need the 64-bit accuracy. Try your calculation both ways with the same data and see how much accuracy 32 bits loses. Of course 64-bit calculations seldom give 64-bit accuracy in the results. I once had an ill-conditioned algorithm that gave negative values of some outputs that had to be positive with 32 bits, a problem that 64 bits cured, results differing in the 4th significant figure from 64 bits with 80 bits, but much further down with 128. (Hurrah for gfortran offering all 4 kinds.)
HY-8 is a 64-bit program, and only compatible with 64-bit Windows-based operating systems. When installing HY-8, make sure you have permissions on your computer to install programs (usually this requires administrator permissions or a username and password for an administrator account). If you do not have administrator permissions on your account, you need to right-click on the installation program and select the "Run as Administrator" option.
So, I tried to find out what type of variable the bitDepth() result provide (double, int, etc) but I found out that all the Numbers are stored in 64-bit double-precision floating point format. (ImageJ Macro Language)
I have the same problem. At first, I tried to improve my math skills and tried to divide on my own. Before I came across a calculator suitable for me, I used a method designed for dividing numbers by decomposing the division procedure into a series of simple actions. A number that is divisible is called divisible. The number by which the division is made is called the divisor. The result obtained from the division is called a quotient.
WorkSpaces virtual desktops come with a set of applications at no additional cost. For an additional monthly fee, you can choose to have 32-bit Microsoft Office 2016 Professional Plus and Trend Micro Worry-Free Business Security installed on your virtual desktop powered by Windows Server 2016. Alternatively, you can install 64-bit Microsoft Office 2019 Professional Plus on your virtual desktops powered by Windows Server 2019.
In the PLAXIS 2D 2011.01 update, Plaxis adds another calculation improvement: the 64-bit calculation kernel. Now larger models can be calculated: in the 64-bit calculation kernel the memory limit is determined by the maximum available RAM memory in the computer system, improving the 2 GB limit of the 32-bit kernel. And in most cases, the 64-bit calculation kernel will improve the calculation time.
In PLAXIS 3D 2010 and later, a 64-bit calculation kernel is available. In order to use such a 64-bit calculation kernel, it must be run on a 64-bits version of a Microsoft Operating System. In that case, the calculation kernel's memory limitation is based on the available RAM in the system, rather than the 32-bit limitation of about 2 GB. These 64-bit calculation kernels are available via the Bentley Geotechnical SELECT Entitlement [GSE] (former PLAXIS-VIP) Licence.
For PLAXIS 3D2010, the system of independent phase calculation is also introduced, so a multi-core processor will have some advantages.
For the best calculation performance using a 64-bit calculation kernel:
With the release of PLAXIS 3D2011, Plaxis will allow for the usage of different solvers, including a multicore 64-bit solver. With this new calculation option, a single-phase calculation can be calculated using multiple CPU cores. For the best calculation performance:
With the release of PLAXIS 3D 2016, the Input/Output GUI, mesh generator and calculation kernel are now all compiled in 64-bit, taking advantage of increased RAM memory usage. Also, the entire geometry model is now taking advantage of a fully parametric geometric data model.
however, you might need to fine-tune the logic - in this version you
can write anything to the calculator like letter characters etc.,
which most lkely can't be handled; probably the logic should be
reversed to only call Skip() on chars, which are meaningful as input
for your calculator; on "functional" characters like + / ... you won't
call event.Skip() but use the corresponding function call instead; the
remaining keys, you are not going to accept as input will be
"swallowed" this way.
I have been learning to program using Python (self-teach) and wanted to
create something useful while learning. I am using wxPython to create the
interface. The calculator uses RPN similar to an HP48 series calculator and
has the display appearance similar to an HP48 as well. The app works if I
use the mouse to click the buttons. I've been trying to get it to recognize
operation key-ins like the addition using the num pad +. It will register
the keystrokes but the binding for the event handler to run the operation
commands isn't working. I originally had it bound to the button then
realized it should be bound to the TextCtrl. When I bind the event to the
TextCtrl, it no longer recognizes any input from the keyboard. I would like
it to recognize key-ins like [enter], +, -, *, and / as operations and not
text input.
MedCalc is available in different versions for 32-bits and 64-bits Windows editions. The 32-bits version will work on both Windows editions. The 64-bits version will work on 64-bits Windows editions only. But if you are experiencing problems with the 64-bits version, you should use the 32-bits version (both have the same functionality).
Windows Calculator is a software calculator developed by Microsoft and included in Windows. In its Windows 10 incarnation it has four modes: standard, scientific, programmer, and a graphing mode. The standard mode includes a number pad and buttons for performing arithmetic operations. The scientific mode takes this a step further and adds exponents and trigonometric function, and programmer mode allows the user to perform operations related to computer programming. In 2020, a graphing mode was added to the Calculator, allowing users to graph equations on a coordinate plane.[3]
The Windows Calculator is one of a few applications that have been bundled in all versions of Windows, starting with Windows 1.0. Since then, the calculator has been upgraded with various capabilities.
The calculators of Windows XP and Vista were able to calculate using numbers beyond 1010000, but calculating with these numbers (e.g. 10^2^2^2^2^2^2^2...) does increasingly slow down the calculator and make it unresponsive until the calculation has been completed.
In every mode except programmer mode, one can see the history of calculations. The app was redesigned to accommodate multi-touch. Standard mode behaves as a simple checkbook calculator; entering the sequence 6 * 4 + 12 / 4 - 4 * 5 gives the answer 25. In scientific mode, order of operations is followed while doing calculations (multiplication and division are done before addition and subtraction), which means 6 * 4 + 12 / 4 - 4 * 5 = 7.
