  • Maximize a floating div?

    - by hhj
    Say I have 2 divs side by side: 1 float left, and the other float right. Now say I fix the size of the left floating div to say 200px. How do I force the right floating div to "maximize" itself or occupy the rest of the horizontal screen space (regardless of the size of the browser window?

  • Deterministic floating point and .NET

    - by code2code
    How can I guarantee that floating point calculations in a .NET application (say in C#) always produce the same bit-exact result? Especially when using different versions of .NET and running on different platforms (x86 vs x86_64). Inaccuracies of floating point operations do not matter. In Java I'd use strictfp. In C/C++ and other low level languages this problem is essentially solved by accessing the FPU / SSE control registers but that's probably not possible in .NET. Even with control of the FPU control register the JIT of .NET will generate different code on different platforms. Something like HotSpot would be even worse in this case... Why do I need it? I'm thinking about writing a real-time strategy (RTS) game which heavily depends on fast floating point math together with a lock stepped simulation. Essentially I will only transmit user input across the network. This also applies to other games which implement replays by storing the user input. Not an option are: decimals (too slow) fixed point values (too slow and cumbersome when using sqrt, sin, cos, tan, atan...) update state across the network like an FPS: Sending position information for hundreds or a few thousand units is not an option Any ideas?

  • Make div expand only horizontally when more floating divs are added to it

    - by Wesam
    I am trying to make a div that contains other floating divs to adjust its width such that adding more floating divs (dynamically using jQuery) will only expand the div in its width, not allowing the floating divs to create a new line. Therefore, I want to fix this issue such that each div with class grid-row only expands in width, and so I will be able to scroll using the overflow: scroll for the parent grid div. I have searched a lot for answers, and it seems that it is a famous issue. However, non of the answer solved my problem. I am currently doing this: <div id="grid_container"> <div id="grid"> <div class="grid_row"> <div class="module" id="experience"> Experience </div> <div class="header"> Google </div> <div class="header"> Microsoft </div> </div> <div class="grid_row"> </div> </div> </div> CSS: body { } #grid_container { margin: 50px auto; width: 500px; height: 500px; padding: 10px; border: black solid 1px; } #grid { overflow:scroll; height: 100%; } .grid_row { clear: both; height: 50px; } .module, .header{ padding: 10px; float: left; border: gray solid 1px; }

  • How can I view an R32G32B32 texture?

    - by bobobobo
    I have a texture with R32G32B32 floats. I create this texture in-program on D3D11, using DXGI_FORMAT_R32G32B32_FLOAT. Now I need to see the texture data for debug purposes, but it will not save to anything but dds, showing the error in debug output, "Can't find matching WIC format, please save this file to a DDS". So, I write it to DDS but I can't open it now! The DirectX texture tool says "An error occurred trying to open that file". I know the texture is working because I can read it in the GPU and the colors seem correct. How can I view an R32G32B32 texture in an image viewer?

  • Will fixed-point arithmetic be worth my trouble?

    - by Thomas
    I'm working on a fluid dynamics Navier-Stokes solver that should run in real time. Hence, performance is important. Right now, I'm looking at a number of tight loops that each account for a significant fraction of the execution time: there is no single bottleneck. Most of these loops do some floating-point arithmetic, but there's a lot of branching in between. The floating-point operations are mostly limited to additions, subtractions, multiplications, divisions and comparisons. All this is done using 32-bit floats. My target platform is x86 with at least SSE1 instructions. (I've verified in the assembler output that the compiler indeed generates SSE instructions.) Most of the floating-point values that I'm working with have a reasonably small upper bound, and precision for near-zero values isn't very important. So the thought occurred to me: maybe switching to fixed-point arithmetic could speed things up? I know the only way to be really sure is to measure it, that might take days, so I'd like to know the odds of success beforehand. Fixed-point was all the rage back in the days of Doom, but I'm not sure where it stands anno 2010. Considering how much silicon is nowadays pumped into floating-point performance, is there a chance that fixed-point arithmetic will still give me a significant speed boost? Does anyone have any real-world experience that may apply to my situation?

  • Floating Tables Problem Unwanted Space XHTML Strict

    - by Axel Myers
    Hi I have two floating tables side by side. One is set to float left, the other one is set to float right. The problem is when two table are floating, they both are out of flow so next table comes without any spacing. So I add a width attribute clear:both. But now it gave me a lot of unwanted space! it's height set to:0 (the div's) and nothing has changed. So what's the problem ? Website url: http://www.animetr.com/prv/

  • Floating point Endianness?

    - by cake
    Hi I'm writing a client and a server for a realtime offshore simulator, and, as I have to send a lot of data through a socket, I'm using binary data to maximize the ammount of data I can send. I already know about integers endianness, and how to use htonl and ntohl to circumvent endianness issues, but my application, as almost all simulation software, deals with a lot of floats. My question is: Is there some issue of endianness whean dealing with binary formats of floating point numbers? I know that all the machines where my code will run use IEEE implementation of floating points, but is there some endianness issue when dealing with floats? Since I only have access to machines with the same endian, I cannot test this by myself. So, I'll be glad if someone can help me with this. Thanks in advance.

  • OpenStack: How to make Cloudify use the floating IP instead of the fixed one?

    - by polslinux
    I have a problem with Cloudify (both 2.5 and 2.6-rc release). I have an All-In-One Openstack 2013.1.1 setup and I'm trying to use Cloudify to bootstrap a cirros 0.3.1 vm. My quantum configuration is: pool of fixed ip (10.0.0.0/24) for vm management; pool of floating ip (192.168.1.170-190) taken from 192.168.1.1/24 (my lan) When I deploy a vm first, an ip from 10.0.0.0/24 is given (I cannot reach it from my PCs because it is only for vm management) and then I associate a floating ip with which I can ping (and ssh) the deployed machine. The problem is when I do: bootstrap-cloud openstack because Cloudify stay forever into "attempting to access management vm 10.0.0.3" and this is due to the fact that 10.0.0.3 is not reachable. What can I do to get Cloudify take the floating ip instead of the fixed one?

  • ui header is blocking a div

    - by Tumharyyaaden
    i have built jQuery drop-down menu which is having problems floating over the UI header. Flash and everything else is fine, menu has no problem floating over anything except UI headers, i have tried messing with z-index in css files but it seems that jQuery script is over writing all of my css. the JS files are minified so i can not edit them. I think a JS solution is necessary but i do not know how to solve this with JS. URL: http://patel.mine.nu/live%20site/metanoia/

  • easy hex/float conversion

    - by yeus
    I am doing some input/output between a c++ and a python program (only floating point values) python has a nice feature of converting floating point values to hex-numbers and back as you can see in this link: http://docs.python.org/library/stdtypes.html#additional-methods-on-float Is there an easy way in C++ to to something similar? and convert the python output back to C++ double/float? This way I would not have the problem of rounding errors when exchanging data between the two processes... thx for the answers!

  • Strange(?) Opera Floating

    - by SkaveRat
    I have some strange floating behaviour on opera (IE f's up completely different, but that's for later). I'm floating the i-icons to the right. It works nicely on Fx and WebKit, but opera shifts the icons down a bit. Anyone got an idea how this happenes? CSS: .dataRow { margin: 5px 0; clear:right; } .dataRow label{ display: block; float:left; width: 160px; vertical-align: middle; font-size: 80%; } .dataGroup a img { border:0;float:right; position:relative; right:0; } .dataGroup a:hover { background:#EBEDC7; text-decoration:none; } .dataGroup a.tooltip span { display:none; padding:2px 3px; margin-top:20px; width:100px; font-size: 80%; } .dataGroup a.tooltip:hover span { display:inline; position:absolute; border:1px solid #632D11; background:#C2BD6C; color:#fff; } HTML: <fieldset class="dataGroup"> <div class="dataRow"><label>Foobar:</label> <input name="foobar" size="10" value="somedata" /> <a href="#" class="tooltip"><img src="/img/admin/information.png"/><span>Tooltip Info</span></a></div> </fieldset>

  • Compression algorithm for IEEE-754 data

    - by David Taylor
    Anyone have a recommendation on a good compression algorithm that works well with double precision floating point values? We have found that the binary representation of floating point values results in very poor compression rates with common compression programs (e.g. Zip, RAR, 7-Zip etc). The data we need to compress is a one dimensional array of 8-byte values sorted in monotonically increasing order. The values represent temperatures in Kelvin with a span typically under of 100 degrees. The number of values ranges from a few hundred to at most 64K. Clarifications All values in the array are distinct, though repetition does exist at the byte level due to the way floating point values are represented. A lossless algorithm is desired since this is scientific data. Conversion to a fixed point representation with sufficient precision (~5 decimals) might be acceptable provided there is a significant improvement in storage efficiency. Update Found an interesting article on this subject. Not sure how applicable the approach is to my requirements. http://users.ices.utexas.edu/~burtscher/papers/dcc06.pdf

  • Why can't decimal numbers be represented exactly in binary?

    - by Barry Brown
    There have been several questions posted to SO about floating-point representation. For example, the decimal number 0.1 doesn't have an exact binary representation, so it's dangerous to use the == operator to compare it to another floating-point number. I understand the principles behind floating-point representation. What I don't understand is why, from a mathematical perspective, are the numbers to the right of the decimal point any more "special" that the ones to the left? For example, the number 61.0 has an exact binary representation because the integral portion of any number is always exact. But the number 6.10 is not exact. All I did was move the decimal one place and suddenly I've gone from Exactopia to Inexactville. Mathematically, there should be no intrinsic difference between the two numbers -- they're just numbers. By contrast, if I move the decimal one place in the other direction to produce the number 610, I'm still in Exactopia. I can keep going in that direction (6100, 610000000, 610000000000000) and they're still exact, exact, exact. But as soon as the decimal crosses some threshold, the numbers are no longer exact. What's going on? Edit: to clarify, I want to stay away from discussion about industry-standard representations, such as IEEE, and stick with what I believe is the mathematically "pure" way. In base 10, the positional values are: ... 1000 100 10 1 1/10 1/100 ... In binary, they would be: ... 8 4 2 1 1/2 1/4 1/8 ... There are also no arbitrary limits placed on these numbers. The positions increase indefinitely to the left and to the right.

  • Need to place a floating modeless form over excel main window (quasi-task pane)

    - by code4life
    Hi I need to emulate a task pane by floating a modeless form over the Excel main window. The reason for this requirement is that I need to have taskpane features for my Excel 2003 add-in, but cannot use the document-centric model. Can anyone suggest what would be the best way to do this? The modeless form would need to detect the main window resize event and resize itself accordingly, and also need to always position itself at the bottom of the window (kind of like a docking pane).

  • drawing circle without floating point calculation

    - by zaharpopov
    This is common interview question (according to some interview sites) but I can find no normal answers in Internet - some are wrong and some point to complex theory I expect not looked for in interview (like Bressenham algorithm). The question is simple: The circle equation is: x^2 + y^2 = R^2. Given R, draw 0,0-centered circle as best as possible without using any floating point (no trigo, square roots, and so on, only integers)

  • How to make floating frames with wx.aui.AuiManager be proper windows

    - by jhaukur
    Hello all I'm using wxPython. I'm trying to figure out how I can change the behavior of the wx.aui.AuiManager so that when a window is dragged to become floating, it will become a proper window with Minimize and Maximize buttons and shown in the Taskbar. Apparently there is some subclassing done of the standard window to remove those exact features but I'm not having any luck in getting them back.
