Format functions - Improvement request

Question

Hello all,
I have request for update.
I.e, i have some site that deals with the products, all products have price, discount, quantity and VAT.
I want to all prices be formated like this: 123,298.23
I have to create functions:
function formatNumber(nStr){
nStr = parseFloat(nStr);
nStr = nStr.toFixed(2);
nStr += '';
x = nStr.split('.');
x1 = x[0];
x2 = x.length > 1 ? '.' + x[1] : '';
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1)) {
x1 = x1.replace(rgx, '$1' + ',' + '$2');
return x1 + x2;
function formatVPC(region, lookupFunc)
var nStr = lookupFunc('{dsStavkeNarudzbenice::price}');
return formatNumber(nStr);
And to do this:
{function::formatVPC}
and if i calculate total like price* quantity i have to add new
function formatPrice*Quantity(region, lookupFunc)
var nStr = lookupFunc('{dsStavkeNarudzbenice::jedinicna_cena}');
return formatNumber(nStr);
Why Not {price| formatNumber}?
Something like Smarty formating, with possibility to add params, like {price|formatNumber, ',', "."} - where  i want to use  , for 1000 separator and . for decimal separator?
Then I can use just one function for all project, without creating additional separators.
Creating small math expressions ?
Now, I can not do this:
Total Sum is {price}*{quantity}
Why not:
Total Sum is {eval|'{price}'*'{quantity}'} or some other solution?
Rationale:
It decrease code, it does not inflicts with application logic, it is more usable and readable
