How to do Number.toFixed

[Tarler]

Hello,

Is there a best way to get Number.toFixed using Haxe? I can't find it in anywhere in the existing core API

Suggestions like the following, to multiply and divide by a precision factor, do not work for all numbers

http://lists.motion-twin.com/pipermail/haxe/2006-June/002592.html

 var input:String = "2495.70";
 var parsed:Float = Std.parseFloat(input);
 trace("parsed:" + parsed);//2495.7
 var product:Float = parsed * 100;//do something with our float
 trace("product:" + product);//249569.99999999997, would expect 249570
 var prec = 100;
 trace("rounded:" + Std.int(product*prec) / prec );//249569.99

To get around this, I am just getting access to the "native" toFixed method in a roundabout way, but this will surely break on targets other than Flash and Javascript

 public static function toFixed(x:Float, decimalPlaces:Int):String {
 var f = Reflect.field(x, "toFixed");
 return Reflect.callMethod(x, f, [decimalPlaces]);
 }

Any ideas appreciated.

Thanks,

James
