1. не понятна проблема. у меня работает numpad
2.

num = 0.123453;
floor2 = function (num, r) {
	var degree = Math.max (1, Math.pow (10, r));
	return Math.floor (num * degree) / degree;
};
round2 = function (num, r) {
	var degree = Math.max (1, Math.pow (10, r));
	return Math.round (num * degree) / degree;
};
ceil2 = function (num, r) {
	var degree = Math.max (1, Math.pow (10, r));
	return Math.ceil (num * degree) / degree;
};
for (i = -1; i < 8; i++) {
	trace ("знаков после запятой : " + i);
	trace (floor2 (num, i));
	trace (round2 (num, i));
	trace (ceil2 (num, i));
	trace ("");
}
