JavaScript - Modulus Operator Is Not Working If I Give Number More Than 24 Digits
If number is more than 24 digits, modulus operator is not giving correct output
here attached sample code [code]<script type="text/javascript"> var a=10000000000000000000000.0; var b=10.0; var c=a % b; alert("c"+c); </script>[code] please tel me solution Similar TutorialsOoook so this is probably the stupidest question ever. I know in java you can take advantage of a number being an int (not double) and divide by something without getting a remainder. But in javascript you dont declare what kind of variable something is. So my problem is: Given any double or triple digit number, how do i get all but the last digit. Like if i have 13, I need to make an int with 1. If it's 103 i need one with 10. Thanks!! I'm trying to create a modulus function that will redirect users who input certain values to a secondary page. I've searched google and found a way to validate when users input a multiple of x, but I need to take it one step further and only allow values within a certain range. In full, I need to validate multiples of 7 starting at 7007 and ending on 15673 (so validate on 7007, 7014, 7021, etc.). Right now I'm looking at this code: Code: $(document).ready(function(){ $(".sub").click(function(){ if (!(($(".txt").val() % 7 == 0) || ($(".txt").val()==1))) { alert("Not interval of 7 or value of 1"); } else { alert("Interval of 7 or value of 1!"); } }); }); Which I found here. I also need to remove the "value of 1". I'm new to JS, so when I tried, I broke the code. Any help would be much appreciated. Thank you!

Thanx Disregard - I believe I have figured it out finally!! hi, i'm trying to keep a copy of a variable at 4 digits.. this is what i came up with.. it's working but i'm only a noob, so i would very like to know is there any other simpler and/or elegant way to do this.. also i would appreciate it if you could point out any bad syntax or something.. Code: page = 100 function makeit4digits(){ page4digit = page if (page<10) { page4digit = "000"+ page } else if (page<100) { page4digit = "00"+ page } else if (page<1000) { page4digit = "0"+ page } } Hello all I'm trying to get this function to check for 10 digits only but alert shows regardless of less / more or exactly 10 digits --- what am I missing? any help on sorting this greatly appreciated.

On an image slideshow, there is a counter at the bottom showing what image it is up to (ie 7/15), I'm not entirely sure how to change this into double digits (ie 07/15) I've found this thread (http://www.codingforums.com/showthread.php?t=212321) but am unsure how to integrate it into the slideshow I'm using, which is a different one. Here is the part from my JS I think that needs modifying: Code: if (setting.displaymode.type=="manual" && !setting.displaymode.wraparound){ this.paginatecontrol() } if (setting.$status) //if status container defined setting.$status.html(setting.curimage+1 + " / " + totalimages) Is this the right bit of code?

I am working on my personal portfolio site, and am using a code that will make each portfolio piece appear in a new div when the name of the piece is clicked on. The problem is, JS does not seem to recognize double digits. I am not familiar with JS at all, I just got comfortable with CSS/HTML a few weeks ago! I am in over my head. It would really, really help if someone could show me how to change the code so that I could make about 15 to 20 divs instead of 9. Here is the code: Code: <script language="JavaScript"> numdivs=9 IE5=NN4=NN6=false if(document.all)IE5=true else if(document.layers)NN4=true else if(document.getElementById)NN6=true function init() { showDiv(0) } function showDiv( which ) { for(i=0;i<numdivs;i++) { if(NN4) eval("document.div"+i+".visibility='hidden'") if(IE5) eval("document.all.div"+i+".style.visibility='hidden'") if(NN6) eval("document.getElementById('div"+i+"').style.visibility='hidden'") } if(NN4) eval("document.div"+which+".visibility='visible'") if(IE5) eval("document.all.div"+which+".style.visibility='visible'") if(NN6) eval("document.getElementById('div"+which+"').style.visibility='visible'") } </script> Thank you for taking the time to read this! Hopefully someone can help.

So far I've logged forty hours in total trying to locate and fix the major problems in this code. I've worked with two other forums and a pay-by-minute guru to no avail. I am hopeful that the good folks here at CodingForums will be able to take this code the final distance. I'll try to be verbose without boring anyone. Summary: This code was written in 2005/2007 by "Wonder" at ProBoards. I teach a fourth grade game design and applied mathematics class to home-schoolers on a ProBoards forum. It is placed in the global footer of the forum to allow forum members to roll dice in their posts. The code was incomplete. I worked with "Jordan" at ProBoards to fix the parts that were incomplete. A problem with the code resulted. Primary resolution I'm seeking: Right now the code does everything I could possibly want. However, it is mistakenly reading double-digit numbers (XY) as X = sides of die and Y = a negative modifier. Once this issue is fixed, I can take the roller back to my students and they can game together. Secondary resolutions I'm seeking: (1) I've been told twice that the code should be "tabbed out." Not sure what that means but I guess it makes it less messy. (2) When clicking the "Add Tag" button the code generates, it automatically inserts [dice=6] into a forum post. Would love this to simply be [dice=X] The original code from "Wonder": Code: <style type="text/css"> .dicebg {background-color: FFFFFF;border:solid 2px #000000;} .dicefont {background-color: FFFFFF;color: 000000; font-weight:bold;} </style> <script> //Dice Rolls In Posts v1.1 updated 31 October 2008 //Copyright 4-23-2007 ~Wonder //May be reposted anywhere as long as this header remains in tact //Do you want the dice to line of horizontally(true) or vertically(false) diceAlignment=true; //Enter URL of the image you want to appear as the dice ubbc button UBBCdiceImage="http://img100.imageshack.us/img100/6118/diceicon9rx.gif"; //Enter the default # of sides defaultSides=6; //Enable dice in preview?

Once installed on a forum, it allows users to type the command [dice=X] where X is the number of sides for the single die they want to roll and it gives them a random result that's very attractive (a small white box with a black border and a bold, large result with smaller text below that reads: Xsides) and not "easy" to change/alter/cheat. To roll more than one die, you simply string the command like [dice=X][dice=X][dice=X][dice=X]. The code also allows for positive modifiers (bonuses) such as [dice=X+Y] where the result has the same compact, attractive format and the small text reads: Xsides+Y Wonder posted that his code would also allow negative modifiers (penalties) but, actually, no one seems to have ever tested that part... until September 2009 when along came pesky me. I went over to the ProBoards support forum because Wonder's code is included in their official database. I posted the problem and a user named Jordan tweaked the code several times, each time getting it closer to providing the correct result. The correct result being that when a user types the command [dice=X-Y] the result is the attractive box, the larger number above and the smaller text below that reads Xsides-Y (in addition to continuing to accept [dice=X] and [dice=X+Y] and offer the same format of results). Jordan's version of the code now does all this. But when I started testing it I realized that whenever a user types a command that gives the die double-digit sides (10, 12, 20, etc), the code now reads it like this: [dice=10] results in 1sides-0 or [dice=12] results in 1sides-2. So double-digit numbers are being read as the number of sides and a negative modifier *sigh* Very bad news. Jordan needed to pass on further work on the code because (understandably) it was taking too much time and it was "messy." Since I am not a coder myself, most JavaScript looks messy to me but I believe Jordan. I then took the code to a pay-by-minute help website but was gently told that the code was so messy that it would take too long to debug and it wouldn't be worth the charge since the roller is being used for a non-profit classroom project for my fourth graders. I thought that was very thoughtful... but I'm back at square one, really. I have attached everything I have: The very original code from Wonder (the one that doesn't read negative modifiers at all) and the latest from Jordan (that reads double-digits incorrectly). The only other cute/attractive thing about the code that I'll point out (so you don't see it in the code and wonder, "What the heck is that?" is: When you install the code into a forum, it adds a tiny die-shaped button to the Add Tags menu. Users can click the little thing and the code automatically inserts [dice=6] for them. Personally, this doesn't help my students and I would love it if the button just inserted [dice=X] but that's fine. *deep breath* Whew! That's about it. Thank you for putting up with my blather. I sincerely appreciate any help you can offer. I know your time is valuable and I've taken quite a bit just posting my full report... I just wanted to try to be verbose :) Jennifer I'm trying to not allow my users to enter in n/a in my form ex... "N/A" "n/A" "na" My code trips the alert every time no matter what is entered in the cell... Why is it doing that? Code: function appliance() { if (document.ComplianceForm.Appliance.value=="n/a" || "N/A" || "n/A" || "N/a") { alert("You cannot enter any variation of n/a in this cell.") } else { return false; }; } Hello I have a question which has been bugging me for a while now so have decided to ask it on CF. In PHP you can use the '&' symbol as a function operator for example like so. PHP Code: function demoFunc(&$output='') { for($i=1;$i<count(func_get_args());$i++) { $output .= ' '.func_get_arg($i); } $output = trim($output); } As you can see the '&' symbol was used in the argument section to allow the function to be used like this demoFunc($output,'hello','world'); print $output; My question is how can I do this in JavaScript to do the same thing like use the variable used in the function argument section and use it like it would be used in PHP? Thank you - DJCMBear I read somewhere (I think from Douglas Crockford) that void is a completely useless operator. What is its actual purpose? Is there anything it's good for? I see lots of javascript:void(0) hyperlinks all over the place. From what I gather, it just disables the link's default behavior...buy why not just make the href="#" or return false from an onClick handler? Can anyone enlighten me? Code: this.delete = function(obj) { .. Is that it ? I can't have delete ? Or can this be written in some other way, including delete ? I'm still learning js core using Flanagan's 5th ed. so please bear with me; is the if ("ignore" in arguments.callee) return; below valid or a typeo? Thanks J. Code: function inspect(inspector, title) { var expression, result; // You can use a breakpoint to turn off subsequent breakpoints by // creating a property named "ignore" on this function. if ("ignore" in arguments.callee) return; ....... |
