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"

How do I do this in JavaScript ?

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.

I want javascript function that could convert from integer to float e.g if user enters 10 then it should convert it to 10.00 or better 10.000. If user enters 10.0123 then it should convert it to 10.0123.

I am trying to use the following javascript [URL] to create something similar to the example on [URL] for a school project but I wondered if someone could advise me how I can round numbers to 2 decimal places in the field box as I have to convert the calculated value by an exchange rate, e.g.:

where x=100 and y=50

calculate="(x+y)/1.55"

returns a value of 96.77419355. I would like to round this figure up to 2 decimal places so it would read 96.77 but I cannot figure out how to do this.

Is there a code that changes decimal places? Example if you have 333.333333..... can you make it say just 333

View 2 Replies View RelatedI am looking to enforce the use of 3 decimal places in an input. I have found some scripts that do this, however, I also want to format it this way in case someone enters LESS than 3 decimal places. If a user enters 1.25, I want it formatted as 1.250 If a user enters 1 I want it formatted as 1.000 etc.

View 4 Replies View RelatedMy javascripting is getting there, I have been learning for the last week and I have produced a working script however im getting stuck with how you round a variable (stored user input) up to the nearest whole number to 2 decimals I have looked at many tutorials and I think that the math.round has to be used somewhere but I cannot work out the syntax to integrate it into my code because everywhere I have looked seems to be using document.write syntax:

I am new to javascript and I am attempting to output to two decimal places as its currency. As an example it currently outputs as 127.1 instead of 127.10.

rounding the quote up to two decimal places. I've seen a lot of codes and tried a bunch (math.round, tofixed, toprecision) but not exactly sure how to use them and where to put them. Calculator can be viewed here along with the code [URL]

View 3 Replies View RelatedI have a small piece of code (taken largely from W3 Schools)that checks that there is a decimal point entered in a form field, but what I really need is to check that the number entered ends in 2 decimal places.

e.g.

10 is Invalid

10.00 is Valid

My current code is below. Can someone explain what I need to do to ensure that the user enters a number including two trailing decimal places please?

function AddDays(days) {

var thisDate = new Date();

thisDate.setDate(thisDate.getDate() + days);

return thisDate;

}document.write(AddDays(366))

</script>

I 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?

Is there a JavaScript method to convert a "plain" number into a decimal one?

View 1 Replies View RelatedHi All, I am trying to program a web based cash register/POS application. I would like to use a function to format the number in the "Amount Received" text box.For Example: if someone typed in 2000 it would automatically change that to 20.00

I would probably be triggering the function via onkeyup so it would actually change it on number at a time. 2->.02, 20->.20, 200->2.00, 2000->20.00 ect.I know I could do it in php when processing the form, but I would really like the number to be already formatted when the form is submitted.

Is there a formatting or rounding technique to specify the number of digits to display after the decimal?

<script type="text/javascript">

function updatesum() {

document.PaymentForm.newbalance.value = (document.PaymentForm.balance.value -0) - (document.PaymentForm.paymentamount.value -0);

I want to round the value of document.PaymentForm.newbalance.value to two decimal points.

How do I separate the integer and decimal part of a number, ie. If I had

123456, and divided it by 1000 = 123.456,

how do I obtain 123 and 456 as seperate variables?

This is the sort of thing that is done using the "int" and "mod" function

in Excel...

I'd like the posted result to be a number with two decimals. I know how to make this normally but not with this kind of script.

function calcResult(){

document.getElementById('result').innerHTML = '';

[Code]....

Tell me how to make decimal points an exception to the non-number pattern?code...

[code]....

how to approach this but I have a date input that uses a jQuery pop-up for a calendar, and enters the date in a format d MMM yy (1 Jan 11).

Not everyone wants to be clicking and choosing the date from the calendar but to be entering it just as a number such as 0101, 010111 or 01012011 which can be faster. This would then need to be converted to the d MMM yy format as per the jQuery pop-up when they exit the input box.

So really only if it's a number format it needs to look at the number of digits... and does the conversion.

Has anyone done something like this before? Or is there a link to how I could go about achieving this?

When I try to add a variable and a number from a textbox they add as strings:

Now when I add number to it I get an error in the page:

I am sure all the other code is correct.

How do you change a variable into a number format?
