i have some file size in bytes, and i want to get it in KB or MB, with
one decimal digit, for example:1268777 -> 1.2 MB
now i can have 1.210000... my question is how do you can round this number properly, if i use Math.round(number), i only get 1 MB
I need help with figuring out how to round to the nearest 5th number.For example, if I had a variable with the value of 42, how can I round that up to 45; another example being 37 to 40.
View 9 Replies View RelatedI have a order form that adds up all the input boxes (45) and then totals them using function updatePrice() (which works) Im trying to have the output as XX.XX and cant figure out how to get the number from the id=txtTotal into the function round() and return the formatted number to txtTotal.

I have to round a fractional value from a form input to either 0, 25, 50 or 75. I have succesfully tested the value and stripped the decimal place. If the value is for example .1, I round it to 0. If the value is say .2, I round it to .25. My problem is that when the value is > .75, my function is returning undefined. For the sake of brevity I will include only the relevant code.
var increments = new Array(0,25,50,75);
CharBefore = parseFloat(CharBefore); //the whole number
CharAfter = parseFloat(CharAfter); //the decimal
var x = parseFloat(increments.length - 1) ;
for ( i = 0; i <= x ; i++ ) {
var testValue = parseFloat(increments[i]);
if (CharAfter > testValue) { continue ; }
else {
var lowerValue = parseFloat(increments[i-1]);
if ((CharAfter > testValue) && (i==x)) {
median = (testValue + 100)/2 ;
if (CharAfter >= median) {
CharAfter = Ɔ'
CharBefore++;} //round up to next whole number
else { CharAfter = testValue; }
}
else {
median = (testValue + lowerValue)/2 ;
if (CharAfter >= median) { CharAfter = testValue; }
else { CharAfter = lowerValue; }
}
return CharBefore + '.' + CharAfter;
break;
}
} // End for loop
Is there a script that will round off a number to a certain number of
decimal places?
The inputs for the fields of mth6, mth12, mth18, mth24, set50, set75, set 80 and set85.
I would like a way for it to round up to the nearest tenth.

My problem here is that I am calculating the percentage values of a whole number and storing those values in text boxes respectively through javascript function.Now,what I need is that I want to round all the values to integer value such that the sum of integer values is equal to the final value.
So just found out the problem I was having, and came up with a solution (bandaid really) but would like to know if anyone else has run into this and what they did.
Code JavaScript:
var left_margin = $(this).css('margin-left').replace(/D/g,'');
So the above, get the left margin of the object, strip all but numbers and store into a variable. Easy, right? Here's what happened. Inserted the object into the DOM, Chrome returned 212px, which was converted to 212�*fine. Firefox on the other hand returned 212.5px, which was converted to 2125� not fine. I'm centering the element on the screen based on this number, so the additional 2000ish pixels is WAY off. My solution was to increase one of my initial values a single pixel in which both browsers return 213px�*but like I said this is only a bandaid solution. Not really understanding the value of .5 pixel, but looking into that. Is there a rounding function in jquery? Javascript I would have to strip the px from the string, convert to integer and THEN round.

I have a half dozen bookmarks for rounded corner plugins, but am wondering if there's a "state of the art" plugin kicking any booty on that these days? What I'd *really* like is to just be able to set -moz border radiuses in CSS and have a plugin magically use those to create rounded corners in IE and Safari (IE mainly... using excanvas or something with it is fine, too).
View 6 Replies View RelatedSuppose I do (5 * 0.039) + 0.59, then the result is 0.7849999999999999 - but I want to round it upwards and should have only 3 digits after decimal point. I found out that using toFixed(3) will get it to be 0.785, but the problem is that it add x.x00 for some numbers where there aren't much decimal numbers. Is there a way I can remove the 0's?

I am using the standard Bingo Card Generator and it works great however, I need help coding the script so that the number are associated with a picture for example everytime number 12 would show up on the card an image would replace the number. Here is the code that I am using:

When updating our agency's webpage daily, [URL] I am looking for a shortcut to save time.. When I update air quality numbers. I have to put the conditions. Ex.. 50 = good 100= moderate etc etc. As you see here(bold and underlined)
[Code]...
Well instead of having to type good or moderate every-time to correlate with the numbers, I want to find a way the category can automatically default correctly when I put in just the number. Ex, if I put in the number 100, it automatically knows to issue/ put Moderate with out me having to type it. I semi wrote a code .. Yet can't seem to know how to execute. Seeing if Maybe I can get some assistance.

I have a function below where every time a question is submitted, it will add a new row in the table with a textbox which allows numbers entry only. My question is that I don't know how to code these features in this function:
I want the text box to be between 0 and 100, so if text box contains a number which is above 100, it will automatically change the number to the maximum number which is 100.
Does any one know how to code this in my function below in javascript:
Code:
When I used toFixed() method on a number, I thought that this method round a number to a specified approximation, but I got a surprising result, the number became string! 15.23689.toFixed(2) ==> "15.24". So does it convert the number into string?
View 6 Replies View RelatedI am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?

Questions:
(1)I wanted to know if code this script so that instead of the phone number appearing as: (123)456-7890
So that it appears as: (123) 456-7890 with a blank space after the ")"
(2)If that's simple, is there a way to error-check it so that only numbers can be entered into the phone number input field?
What i'm trying to do is replacing the size=180 part of the src (in this case an image) with size=400 so that the images appear larger. I can't simply replace any "180" with "800" because the value might be present in the lid or isbn.So far I've pretty much cut the url up in pieces (I reckon it could be done a lot easier), but I'm stuck with replacing it.[code]
View 6 Replies View RelatedFormerly I've been replacing characters with javascript using the following code.
paramString = paramString.split("").join("<sup>");
paramString = paramString.split("").join("</sup>");
So if the user on my website types 52 it would return the following value: 5<sup>2</sup>, or just, 5 how do I detect something like this. if they enter: 5 how can I detect the number "2" and put it superscripted past the number 5. so the javascript reads this: 5 and returns this: 5<sup>2</sup>
I'd like to make a Degree object that inherits from the Number object and uses the Number constructor but adds a .rad() method that returns the value in radians.

I am delving into the coding world and while I understand the basic principle of cookies, conditional statements, arrays, etc...I have looked around the web and this forum with little success. If the situation below is too complicated, I would really appreciate even a shove in the right direction regarding the logic.How could I show a preset counter which counts up from a preset, beginning number toward a preset, end number? I imagine the increment and speed is set be the difference between the two numbers and a timeframe.
:confused: Assumptions:I would rather not set the increment but edit the end number to show a steady increase. As I update that number, the increment adapts dynamically. I would want the number/script to be useful, so it should not refresh to the beginning number on each page load (i.e. num=0). When a visitor comes to the page, it must seem like the counter has been steadily been increasing in their absence.Coke or Pesi did something similar one time regarding cans sold to date (doubt it was plugged into a DB somewhere but rather based on a steady sales figure) and it was pretty cool.
I have a table like this:
<table id="myTable">
<tr><td>text</td><td>text</td></tr>
<tr><td>text</td><td>text</td></tr>
...
<tr><td>text</td><td>text</td></tr>
</table>
Now I want to add a javascript to the page that informs me of which row
I have clicked. If I click the second row it should fire an alert with
"You clicked row: 2". I don't want to add javascript inside the html of
the table.
I have a pdf form that has an invoice number I would like to make the
number in the text field add (1) each time the document open and save
it, so that the next time the document is opened it will display a
consecutive number. Example: 9078, 9079, 9080, 9081...etc.
It's possible to check if it's a valid number in <INPUT...
I try typeof and parseFloat and it's not working. It's seem impossible to
test (with a if) the value "NaN"!!
