it’s not that hard… 😉

```auto
// prototype
Number.prototype.limitDecimals = function(decimals) {
	var str, tmp = this.toString(), dIndex = tmp.lastIndexOf(".")+1, index;
	for (index=0; index<dIndex+decimals; index++) str += tmp.charAt(index);
	return str;
};
// usage
Number.limitDecimals(decimals);
// example
myNumber = 7.7777;
trace(myNumber.limitDecimals(2)); // output: 7.77

```

forget about that… as usual, i like the hard way. 😛

```auto
Number.prototype.limitDecimals = function(decimals) {
	this = this.toString().substr(0, this.toString().lastIndexOf(".")+1+decimals);
	return Number(this);
};

```

that’s much better. =)

theres also

```auto

Number.prototype.limitDecimals = function(depth) {
	var factor = Math.pow(10,depth);
	return Math.round(this*factor)/factor;
};

```

which rounds to that decimal and not just chops 🙂
