Convert an int64 to a float and back

Int64Utils.hx

import haxe.Int64;

class Int64Utils
{
	private inline static var MAX_32_PRECISION = 4294967296;

	public static function fromFloat(f:Float):Int64 {
		return Int64.make(Std.int(f/MAX_32_PRECISION), Std.int(f-(f/MAX_32_PRECISION)));
	}

	public static function toFloat(i:Int64):Float {

		return (Int64.getHigh(i) * MAX_32_PRECISION + Int64.getLow(i));
	}

}

Sadly this doesn't work:

  private inline static var MAX_32_PRECISION:Float = 4294967296.0;

public static function fromFloat(f:Float):Int64

{

var h = Std.int(f / MAX_32_PRECISION);

var l = Std.int(f);

return Int64.make(h, l);

}

trace(fromFloat(Std.parseFloat("5000000000"))); // yields 6442450944 on neko
