It goes up to Illions of numbers (icl. Decillion, Vigintillion, Trigintillion, etc...), This is going to reach Milliillion at 1e+3003, still, yeah! But, it is so big, like the suffix before Mi (Millillion) is so, so long (I really mean it)! Also the length of this is so long, and if you turn on turbo mode it will be too fast and you might get epilepsy!! So don't do that.
