Javascript Round to 2 Decimal Places

Solved

Hello,

I'm looking for a JavaScript function that would round a number to two decimal places (a bit like number_format in PHP), as the round() function only allows rounding to the unit!

Thanks
Ciao

The response is late, but it may help some:

There is no one-size-fits-all method for this, so you have to do 

Math.round(your_number*100)/100;


Otherwise, you can use the Number class and do 

var your_number = 12.3455633; // Your number variable your_number.toFixed(2); //will return 12.35..


There you go for everyone still looking ^^

It's me again, just to say that this method (Number.toFixed()) is JavaScript 1.5 and it only works for IE5.5+ and NS6+

You can do 
if (your_number.toFixed)
to check if it is supported.
