Всем привет.
Есть такой код
private function enterFrameHandler(event:Event):void {
if (omniLight.intensity==ran) ran= Math.round(Math.random()*1/ .01) * .01;
if (omniLight.intensity<ran) omniLight.intensity+=0.01;
if (omniLight.intensity>ran) omniLight.intensity-=0.01;
Math.round(omniLight.intensity/ .01)* .01;
trace ("omni "+omniLight.intensity);
trace ("ran "+ran);
trace("-----");}
и выдает он
omni 0.61
ran 0.75

т.е по началу все идет хорошо но затем округление перестает работать и все стопориться. В чем может быть проблема?
А где Вы увидели округление? Вот это округляет только при соблюдении условия и только часть выражения в процессе рассчетов.
if (omniLight.intensity==ran) ran= Math.round(Math.random()*1/ .01) * .01;
А эта запись
Math.round(omniLight.intensity/ .01)* .01; за горизонтом событий, простите. Даже если компилятор ее оставляет в коде (хотя зачем бы ему?) — это вычисления "в уме", ибо их результат не используется НИГДЕ. Он просто абсолютно никуда не сохраняется.

Спасибо, разобрался
omniLight.intensity=Math.round(omniLight.intensity/ .01)* .01;
if (omniLight.intensity==ran) ran= Math.round(Math.random()*1/ .01) * .01;
if (omniLight.intensity<ran) omniLight.intensity+=0.01;
if (omniLight.intensity>ran) omniLight.intensity-=0.01;
Все-таки кодить до 5 утра плохая практика.

А нет. всеравно ошибка. просто теперь она дольше не проявляется.
omniLight.intensity=Math.round(omniLight.intensity/ .01)* .01;
if (omniLight.intensity===ran) ran= Math.round(Math.random()*1/ .01) * .01;
if (omniLight.intensity<ran) omniLight.intensity+=0.01;
if (omniLight.intensity>ran) omniLight.intensity-=0.01;

Особенности вычислений с плавающей точкой. Вам это мешает? Используйте где можно целые числа (int, uint). У Number такая вот точность.
trace(57 * 0.01); // 0.5700000000000001
trace(57 / 100); // 0.57
Nikirozzz, а зачем умножать на единицу?
Math.random()*1
Elff - для верности :D
С точностью боремся toFixed(2);
