How can I handle large numbers in C?  #include &lt;stdio.h&gt;  unsigned int fb(int val) {    if(val == 1)       return 1;    val = val * fb(val-1); }   int main(int argc, char *argv[]) {  unsigned int rc;   rc = fb(100);   printf("return fib is %lu\r\n", rc);   return 0; }   If C is not a suitable language then what language people do use to handle such large numbers? I am sure using C will have a benefits like timing, performance.
What is the easiest way to handle huge numbers in C? I need to store values in the Area 1000^900, or in more human readable form 10^2700. Does anybody know of an easy way to do that? Any help would really be appreciated!
Intuition for multiple temporal dimensions It’s easy, relatively speaking, to develop an intuition for higher spatial dimensions, usually by induction on familiar lower-dimensional spaces. But I’m having difficulty envisioning a universe with multiple dimensions of time. Even if such a thing may not be real or possible, it seems like a good intellectual exercise. Can anyone offer an illustrative example? Can Blender render pngs with the background transparent? Record Animation In BGE I am having trouble getting the Record Animation setting to work in the BGE. Is it possible to record animated characters that are controlled using BGE's logic bricks with some script? In my script I change the positions of the characters bones. Seem to have lost 4 Silver badges and 10 Bronze badges Does Windows use the fastest drive for the page file? Suppose I have a 6 GB page file on an SSD and another 6 GB page file on a traditional mechanical 5400rpm SATA drive.  Does Windows take into account the difference in the performance characteristics between the two drives when deciding which page file to use?  If it matters, I'm asking about Windows 7 and higher.  I reviewed this  but it doesn't appear to factor in the case of dissimilar storage speeds. I have the following problem.      Let $f:D\to \mathbb C$ be a holomorphic function, where $D=\{z:|z|\leq 1\}.$ Let $$f(z)=\sum_{n=0}^\infty c_nz^n.$$ Let $l_2(A)$ denote the Lebesgue measure of a set $A\subseteq \mathbb C$ and $G=f(D).$ Prove that $$l_2(G)=\pi\sum_{n=1}^\infty n|c_n|^2.$$   After a long struggle I managed to come up with the following formula $$l_2(G)=\iint_D |f\,&#39;(z)|^2dxdy.$$ It looks like the right thing to use because $$f\,&#39;(z)=\sum_{n=1}^\infty nc_nz^{n-1},$$ which is similar to what I have to prove. I understand that the $\pi$ will appear when I integrate something over the angle $\phi$ in polar coordinates. But I don't know how to find the square of the absolute value of the right-hand side to even start integrating...  EDIT: The function is supposed to be  (one-to-one). (I'm not perfectly sure I'm translating the term correctly. The (Polish) word in the statement of the problem was "jednolistna". I have not met it before.) Question from HNQ widget on Android doesn't load, showing last viewed question instead I have found myself in an uncomfortable situation after clicking the Hot Network Question widget.   I click the widget, it opens Stack Exchange app and doesn't refresh. That causes me seeing the question I haven been reading a while ago. Fact is that I haven't killed the app since using it last time.   Is there any known workaround to prevent this bug occurring every time I want to read a question opened from a widget? Killing the app/deleting data every time is not a convenient option.   It happens on all Android devices, so device specs aren't relevant, I guess.   Edit: it isn't reproducible 100% of the time. Sometimes it works. Remove appx package for all users Fresh Windows 10 install. Somehow the MSN Weather app became corrupted. (Unable to launch) I removed the app with the following Powershell command:     Remove-AppxPackage -Package Microsoft.BingWeather_4.7.118.0_x86__8wekyb3d8bbwe   However, when running     Get-Appxpackage –Allusers   the package is still present. When I attempt to reinstall the app via the Windows Store, the download is skipped and the same corrupted package is installed.  I've tried restarting (many times) and using WSReset to no avail.  What can I do? Thank you! Why is the ampere a base unit and not the coulomb? I always thought of current as the time derivative of charge, $\frac{dq}{dt}$. However, I found out recently that it is the ampere that is the base unit and not the coulomb. Why is this? It seems to me that charge can exist without current, but current cannot exist without charge. So the logical choice for a base unit would be the coulomb. Right? Is there an injective function $f :\mathbb{R}^2\rightarrow\mathbb{R}$?  I approached this problem from the perspective of $f^{-1}$, from which I showed there exists a surjective function $f^{-1}:\mathbb{R}\rightarrow\mathbb{R}^2$. Would this imply that there exists an injective function for the inverse mapping? As an example I have a BSB file from NOAA which is a navigational map. The map has a SRS of WGS84 and a Mercator projection.  I initially translate the file from BSB format to GTiff format using the following command:  gdal_translate -of GTiff 18554_1.kap noaa.tif  I can view this GTiff file using Paint Shop Pro quite fine. I then translate the file from GTiff format to VRT format using the following command:  gdal_translate -of vrt –expand rgba noaa.tif noaa.vrt  I then try to generate a tile matrix set using the following command:  gdal2tiles.py noaa.vrt tiles_folder  Where the map tiles are located in tiles_folder. If I try to open the openmaps.html or google.html, the map zoom in and out looks good. However, on tiles generator like MBTiles, I see tiles swap. See the image below. I am pulling my hair off to get the tiles to line up. I am guessing it is projection error. I am not understanding those projection types. It would great someone can explain it while finding the error. I am planning to use on a tiling  like this. By the way, on GDAL how do I specify the BSB (reference) file that is associated with KAP (data) file? I have seen cases where only one BSB file referred by multiple KAP files. 2015 13" MacBook Pro Trackpad and Keyboard stop working I am using a premium legit version of Minecraft that I purchased. I can log into minecraft.net as well as mojang.com but I am unable to login to Minecraft the game through the minecraft.exe or the Technic launcher. The Minecraft servers are up and running fine. My internet connection is also fine. I double checked my credentials and even tried changing my password. I tried using both my username and my email. I tried all of this on two separate accounts that I own. I tried deleting my login, launcher, launcher.pack.lzma, and launcher_profiles.json and then reopening Minecraft. I tried re-downloading minecraft.exe.   Nothing has worked and I seem to have run out of options. I sent a help request to Mojang but in the meantime I was hoping that maybe you guys could offer some advice. I want to Setup GIMP 2.10 on Ubuntu 16.04 (Xenial Xerus) without flatpak.  can it be possible now or on future?? Footnote in tabular environment There are often situations where buying two separate one-way tickets from A to C via B is cheaper than buying a normal multi-leg ticket. This can be especially useful with airlines such as Ryanair, which specifically avoids selling multi-leg tickets.  Is there a search engine which allows one to search for such flights? I wrote a simple backup script which back ups my stuff on a remote server, everything is working great but I'd like to have some sort of report like "backup successful or not".  this is my script   # backup CHECK date1=`date +"%d.%m.%y - %H.%M"` host=`hostname` twdate=`date +"%d.%m"` performtw=`ls -la|grep "tw"|grep "$twdate" &gt; tmp1.txt` echo $performtw if cat tmp1.txt|grep "tw" then echo backup successfull printf "tw backup success!" | mail -s "tw backup check $date1 repor$ rm tmp1.txt else echo backup failure printf "sitename backup failure!" | mail -s "site backup check $date1 repor$ rm tmp1.txt fi exit   But this isn't working really well and I ask you if there's some simpler and more powerful way to do it? Basically it just needs to check if file exists with the name starting xyz and was created at date xyz. I'm using wordpress multiste 3.3.1 I'm not gonna update it in the future. So I disabled all upgrade functions.  I want to remove the wordpress admin bar from both frontend as well as dashboard.  I can remove it from frontend using this code.  add_action( 'init', 'disable_admin_bar', 1 ); function disable_admin_bar() {     add_filter( 'show_admin_bar', '__return_false' ); }   But i couldn't find any solution to remove it from dashboard.   I don't want to use css solution to hide admin bar and I'm ready to edit the core files to remove it  Can anyone help me to remove it completely?. Thanks Allow user to show / hide sites in the android app Feed I am a registered user in ,  and several other sites, only because I had to ask 1 or 2 questions. In general, I have no interests in these sites, so I don't want to see them on my Feed. Is it possible to hide them somehow?   For now, I want to see only 4 sites (could be meta or non-meta) on my Feed. Notifications are not an issue, because I normally don't get any notifications from those not-interested-in-sites; I rarely participate there. My machine has a SSD (fairly small) and a Hard disk (large). I want to have windows and a couple of programs on the SSD but I want to have the documents folders (such as my documents and my downloads) on the HD. I also want the default install directory pointing at the larger HD. Can anyone advise or point me to a relevent guide? Thanks.
