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.
Top number is the full number (Unless it is above Sx) Middle number is number with Abbrevaiton Bottom number is secinetific notation (sorry for my grammar mistakes, I spell long words bad) WARNING: Overtime the top number will get very long.
