Zero, assuming that a zillion is a real number. 00
You cannot know the amount of zero's in a zillion because a zillion is an undetermined number. People only use it to describe large numbers... just like infinity. You can get more information if you type in the question "How many zeros dooes a zillion have?" It's probably the same as your question, but it has more information than I am able to provide. Hope this helps.
Zero, Zenith, zillion (informal).
there is no such thing a a zillion its made up
None. A zillion is not a real number.
A zillion is an undetermined number.
A "zillion" isn't a number.
There is no such thing as the number "zillion". It is used only in slang term, as meaning "many". There is no definite number for zillion, because technically there isn't a 'zillion'.
A zillion is a fictitious name for an arbitrarily large number.
The value of a zillion has not been quantified. You can decide how many.
One zillion is equal to 1x10^bjillion. Therefore, there are a bjillion and two zeroes in the number one hundred zillion.
Does a 'zillion' really exist? I thought it was just an expression, like 'umpteen'.
