Suppose 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 have this js function:
<script type="text/javascript">
function updatesum() {
document.PaymentForm.newbalance.value = (document.PaymentForm.balance.value -0) - (document.PaymentForm.paymentamount.value -0);
}
</script>
I want to round the value of document.PaymentForm.newbalance.value to two decimal points.
I have an input in the form, where i have to do the following validations.
1) see if it is a number
2) allow digit grouping wither like 00,00,000(Asia format) or 000,000,000 (us format)
3) allow 2 decimal points 000,000.00
4) if the money does not conform to this format return false
I am trying to develop a form that can give an estimate to viewers based on their input and I'm having a problem with decimal points. I couldn't find a very good free script online so I've done some work with this one [URL] When you enter 10 in the input box, it calculate 10*19.99, giving 199.9, but I want it to show 199.90. I've tried adding toFixed(2) in there, but I'm not able to get that to work.
View 6 Replies View RelatedI am in the process of using the split function for splitting strings into an array. The problem I am dealing with is how to do this with local language. Not all languages us the space " " delimiter between words to write a phrase or sentence.
I have a list of all of delimiters for english, japanese, chinese, korean in Decimal Code Point format. For example, the decimal code point equivalent for " " is 32. Is it possible to use the javascript split function with decimal code points? If not, how can I reformat them into a format that js would understand?
Tell me how to make decimal points an exception to the non-number pattern?code...

View 2 Replies View RelatedI wrote a regex to edit a decimal number. you're allowed 1,2, or 3
digits before the decimal point, and 0,1,2,or 3digits after the decimal
point. Of course, you can't enter a decimal point without at least a
digit after ("5." is invalid). So here is my regex
pattern=/^d{1,3}(.(?=d))d{0,3}$/
This works fine for every case except an integer. In other words, it
tests false for entering 5, or 567.
I don't see why it tests false for integers. I'm allowing 1-3 digits
before the decimal point, then a decimal point only if the next
character is a digit (the lookahead clause), and then 0-3 digits after
the decimal point.
I've gotten around this problem with other javascript code around
the regex, but I'd just like to know why this "clean" solution doesn't
work.
I need to do javascript money validation for a field. the condtions are
1) depending on the Locale (not sure if this can be done in JS like US,Germany..)
2) verify if it has $,pound symbol, yen symbol..
3) group the digits either like 00,00,000 or 000,000,000
4) accept 2 digits decimal 000,000.00
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

I need to create some code that is similar to photos.com, istock.com, etc., where when you mouse over and image, a new window opens showing an image larger, and closes when you mouse off the original. All of the code I try either keeps the window open when you mouse off, or is blocked by Firefox's pop-up blocker, which photos.com does not.

I can display the value of the following input box with
alert(parent.MyFrame.document.MyForm.MyInput.value );
But if the frame, the form or the input box doesn't exist I get of course an
error message.
How can I figure out before I display the value if the frame 'MyFrame', the
form 'MyForm' and also the input box 'MyInput' exists without getting an
error message?
I am combining a select box enhancer called Chosen from [URL].. and the jQueryUI accordian with toggler from here:[URL].. Now, when I place the chosen plugin inside one of the togler sections, it just doesn't show correctly.
Here is a demo: [URL].. Click on the States section to see the chosen plugin. I can't figure out why it is not displaying correctly. If I use it outside the toggler, it works fine.
Im looking for a js stopwatch that would express a figure input by the end user -
so for example the code could ask 'how many calories do you burn an hour' - user inputs 100
They start the stop watch and the stop watch show both the seconds/minutes increasing, but also show the calories increasing as (input="100"/60)/60
I have a form for taking customer details. Part of the form will allow the user to select some upgrades for their selected product. The upgrades will be displayed in a drop down list with their additional cost. The total cost of the product being ordered will be displayed on the page.
Could someone please advise me on the best way to automatically update the total cost displayed on the page each time an upgrade is selected? I am using PHP for the site but I'm assuming that javascript is the best choice for this.

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 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.

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 RelatedI'm attempting to physically change the index order of the elements returned by a selector.For example, I'm attempting to make it so when someone clicks on a button, it swaps the index position of the element above or below it (depending on which button they press).I tried to assign it using something like $('.draggable :eq(2)').attr('index', 3)But it didn't seem to work. Is there a way to do it using jQuery, or do I have to change it within DOM itself? Or is there another way to do it?
