## Modifying Round Function To Leave Two Numbers After Decimal Point?

May 9, 2010

This sci calculator listed in [URL] has Round function which rounds the result to a nearest integer. I wonder if it possible to easy modify it so that it would leave two numbers after decimal point when it perform rounding? The calculator's script has these codes related to Round:
<INPUT style="WIDTH: 74px; HEIGHT: 31px" onclick="Round()" type=button size=24 value=Round>
And
function Round()
{form1.display.value=Math.round(form1.display.value);}
I tried {form1.display.value=Math.round(form1.display.value,2);}, but it did no do it.

## Round Up 2 Decimal Places

Nov 17, 2011

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.

## Round Variables Up To 2 Decimal Places?

Jan 11, 2010

My 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:

## Regular Expression :: Allow 1,2 Or 3 Digits Before Decimal Point

Jun 8, 2006

I 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.

## JQuery :: DOM Tag Not Found When Select String Includes A Decimal Point / Fix It?

Aug 30, 2010

I am doing some maintenance work on a classic asp web page that displays product information. I am changing how the page looks up the available quantities for the various sizes. The old method used several SQL queries to determine the number of sizes and available quantities and then used those results to build a table on the fly on the page.

My modification consists of a web service that consolidates product size availability from three different sources and delivers the data via an XML formatted return. I have also added DOM tags in the table that is built on the fly that identify each entry with the product id and size. So, for a product that has an ID of "P12345" and a size of "XXL," that corresponding cell in the table gets an id tag of "P12345_XXL."

My jQuery update statements worked just fine using this approach until the sizes included decimal numbers. My example for this is shoe sizes. A size represented by an integer (6,7,8,...,15,16,17, etc.) works fine. A half-size represented by a decimal (6.5, 7.5, 8.5,...) does not. Even though the period is contained within a string value, jQuery doesn't seem to be able to match the value with an id tag - and yes, I have verified that the two (the string that I am giving to the jquery select and the actual tag) do indeed match.

So far, the only work-around that I have come up with is to multiply numeric sizes by 10 and parse as integer values. Is this a "known issue" and is there a more elegant solution topursue?

## Percentages - How To Round Output To Nearest 10s Place

Oct 21, 2009

I'm a bit confused as I'm just learning PHP/Java, and need to display a percentage. I successfully can display a percentage, however, the decimal like any calculate displays .00000012130 whatever sometimes. How can I round the output to the nearest 10s place?
<script language="javascript" type="text/javascript">
var a = "14";
var b = "25";
document.write(parseInt(a) / parseInt(b) * 100);
document.write("%");
</script>
This is the code I use, however, it needs to be modified so that it rounds to the nearest 10 instead of display a decimal.

## Find Request Round Trip Time?

Jun 1, 2011

I was wondering if there is a way to find the total round trip time of a request. Addins like firebug and chromes console show you this round trip time but i was hoping there was a way to extract it from the response itself.

I would also like to know the response time from when the server sent the request and the client received it. I do not think this is possible since the server and client have different timing systems but it would be very useful.
