Limit It To Only 2 Decimal Places Like 95.44?

Jul 27, 2007

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.

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

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.

Enforce The Use Of 3 Decimal Places In An Input

Apr 1, 2011

I 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.

I 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.

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?

Reg Expression For Currency

May 20, 2006

I need a regular expression to format U.S. currency as 1,215.25 (commas and decimals)...if it is not already in that format. It should also allow a '-' sign as the first character for negative numbers. I have looked in the FAQ and through this group, plus the net and cannot seem to find the right example.

Any pointers or solutions appreciated. Thanks. I found the belowposted in this group:

<script type="text/javascript">
var RgX = /^$(d{1,3}(,d{3})*|(d+))(.d{2})?$/

function NewComma(Q) { Q = String(Q)
return (Q == (Q=Q.replace(RgX, "$1$2,$3"))) ? Q : NewComma(Q)

function setFormat(elm){
var frmCurr= NewComma(elm);

a price in pounds, it gives me the price in dollars and euros.

var oldnumber=thenumber;
var decpos=thenumber.indexOf(".");
if (decpos==-1) return oldnumber+".00";
var endstring=thenumber.substring(0,decpos);
return endstring;

function convert_currency(){
dollarval=document.converter.original.value/ConversionFactor(document.converter.sourcecurrency .value);
//document.converter.converted.value=fix(dollarval*C onversionFactor(document.converter.targetcurrency. value),2);

var dollarval= document.form.gbp.value;


function convert_currency_spec(){
dollarval=document.converter.original.value/ConversionFactor(document.converter.sourcecurrency .value);
//document.converter.converted.value=fix(dollarval*C onversionFactor(document.converter.targetcurrency. value),2);

var dollarval= document.form.special_offer_original_gbp.value;
document.form.special_offer_original_usd.value=fix (dollarval*1.85,2);
document.form.special_offer_original_eur.value=fix (dollarval*1.46,2);

I dont know anything about javascript at all so bear with me.Here is part of the code, the piece in red calls for the number. This is what I need displayed with commas, so its easy to read. I have found a few examples on the web but I have no idea how to apply them to this code.

How To Format Currency And Symbols

Nov 5, 2010

I don't really know javascript but I have one to display pricing in a dropdown. Here is what I have. What I would like to change is this.
Currently amounts 0.075 shows as ---> 0.075
4.9999 shows as ---> 4.99
0.1 shows as ---> 0.1
0.095 shows as ---> 0.095

I would like to get the above to show as follows:
0.075 shows as ---> 7.5
4.9999 shows as ---> $4.99
0.1 shows as ---> 10
0.095 shows as ---> 9.5

The first column (pricing data) is a standard format I cannot change so it must stay that way. Here is my code as it is now.
<script type="text/javascript">
function showrate(strValue){
var objLabel = document.getElementById("lblMessage");
if(objLabel.childNodes.length < 1) {
var objNodeValue = document.createTextNode(strValue);
objLabel.appendChild(objNodeValue); .....

Formatting For Currency And Values That = Zero As Blank?

Aug 11, 2011

(previously posted in the wrong forum and re-posted in this one)Hi there, I have scoured the internet looking for the right code but to no avail. I have gotten as far as totaling up my form but now want to format the amounts and total as currency and also want the values that = 0 to just be blank. I have tried to use the code from other solutions (posted on the net) but I just think it is over my head because I cant figure it out. I thought I was close a few times but wasn't able to bring it on home. One of my issues is using somebody's code and not knowing where in my code to place it have tried exhaustively to solve on my own but there is a point.
