Yeah, that's what I mean ;) That's why I explicitly cited IEEE754 in my reply instead of saying something like «heh, you know, it's that weird javascript thing with numbers» :) On Wed, Jul 8, 2009 at 04:53, RobGrobg...@gmail.com wrote: On Jul 7, 9:14 pm, Massimo Lombardo unwiredbr...@gmail.com wrote: [...] As I see you're dealing with cents, money and stuff, I have to remember you that JavaScript use IEEE 754 Floating Points as its own internal number type, so 0.1 + 0.2 !== 0.3: people tend to be very picky when dealing with money, especially if it's *their* money! :) So: be careful.

solved it by myself.
endpreis =Math.round(endpreis*100)/100;
endpreis = endpreis+ foo;
endpreis = endpreis.replace(/ foo/,);
var cent = endpreis.split(.);
if(cent[1].length == 1)
{
endpreis = endpreis+0;
}else{
if(cent[1].length == 2)
{
//schoen so
}else{
endpreis = endpreis+.00;
}
}

This one is more general (and faster, I think: no if-else, no regexp)
Number.prototype.padRight = function (fill) {
var v = this.toString().split('.'), d = v[1] || '';
return (v[0] || '0') + '.' + d + fill.substr(d.length);
}
test1 = 2;
test2 = 3.141592;
test3 = 0.001;
test4 = .33;
test1.padRight('00'); // returns 2.00
test2.padRight('00'); // returns 3.141592
test3.padRight('00'); // returns 0.001
test4.padRight('00'); // returns 0.33
As I see you're dealing with cents, money and stuff, I have to
remember you that JavaScript use IEEE 754 Floating Points as its own
internal number type, so 0.1 + 0.2 !== 0.3: people tend to be very
picky when dealing with money, especially if it's *their* money! :)
So: be careful. And if you're relying on JavaScript logic to handle
people's money, change programming language, JavaScript is not good at
it.

no it's not for money + - money. it's just to show the price of
something - % action in different sizes after selecting something in
dropdown options. everything else is with php of course. but i'll try
your way too. :)

Yes, the functions I've posted are javascript trasposition of php functions. In php exists the number format function: |$number = 1000; echo number_format($number, 2, ',', '.'); // 1.000,00 After including the javascript function I've linked you can use the same syntax.

Number.prototype.padRight = function (fill) {
var v = this.toString().split('.'), d = v[1] || '';
return (v[0] || '0') + '.' + d + fill.substr(d.length);
}
Very elegant solution!!
