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 want to use a result for furtherer calculations but only want the whole number and not the decimal portion. In Excel there is a function "=INT(A1)" this ignores the decimal values in cell "A1",

e.g. if cell "A1=5.345"

and I use the following function in cell "A2" "=INT(A1)*3" I get the result "15"

I want to build a web form that will allow users to enter 3 different numbers and get a result. The answer is arrived at by the following. Enter 3 variable A, B, and C. Then A / B = D. Then C / D = the Answer.Is there a way to set that up as a single click script? Everything I have tried has failed hard.:mad:

I'm new to Javascript, and just trying to make a simple program that adds two numbers and displays the result automatically in the third field without clicking a button "onclick".I have the following so far, but still not working properly: ttp://pastie.org/private/sy8lkdhvfunudvrizbjjca

What I'm looking to do with the following form is when a user inputs a certain length width and depth the output will be set to a certain number of characters. Basically looking to add a zero before an input of a number lower than 10 in two fields (product_number & product_id)

For example if a user inputs:

The output I would like to have would be:

Right now the output looks like this:

The reason for this is so when I sort my products in my shop they will go in the correct numerical order as well as making everything easier to maintain. I only need it to be 2 digits before the decimal point because the max number input will never be over 99...

I have a HTML file where I want to use javascript to generate a random float number between 0. and 1. and if the number is > or = 0.7 I want the background color of the HTML file change from beige to green. Is this stuff easy to achieve in javascript? Im a total javascript

I'm new here, and I'm a programming newb but am very interested in learning and possibly pursuing programming in the future. As such, I'm taking an intro to Javascript class at my university, and our homework is to make a function that when called upon makes a diamond out of *'s. It is supposed to do so by prompting a user for an int and then makes a diamond shaped object with the inputted number of stars in the middle of the diamond. an example of what this would look like (if a user entered in "5" to the prompt):

Multiplication of numbers do not give a right value For eg. 9090909090909.8 * 100 = 909090909090980.1

Why is it so? Is there a way to save the loss of precision. Actually i want numbers to be rouned to the nearest 2 decimal places only so Math.round(9090909090909.8 * 100) / 100 is the formula i am using, and hence the multiplication with 100 was required. Since the multiplication give a faulty value, the final result is also not as expected.

I was suprised with the fact alert(9090909090909.8112) alerts only "9090909090909.8"

Can anyone make a textbox have an ATM style decimal? You know as you type the decimal stays put for example it starts with 0.00 then if keypress 1 is shows 0.01 then if keypress 2 is shows 0.12 and so on. Get it?

I'm gradually changing the color of some list items like this, but since i is decimal, I'm not getting the full Hex range. Is there a simple way to change i to Hex, so I go from 0 to F? Does jQuery have a function to do that?

I am having an issue with converting my decimal to a percentage. Below is my code: (cost * .06) is where the issue is var cost = prompt("What is the cost of your purchase?", "") document.write("Return Value: "+cost,("<br />")); var salestax = cost * .06 document.write("Return Value: "+salestax,("<br />")); var total = cost + salestax document.write(cost + salestax);

If I get a percentage result on a form, for example: 95.44186046511628

Is there a way I can limit it to only 2 decimal places like 95.44? It won't always be 95.44186046511628, so it just wouldn't apply to just that one percentage. I need it to only have 2 decimal places with whatever the value is.
