No, the Ancient Greek number system did not use zero as a place value, or number for that matter.
You would say this number as "zero point zero two zero" or "zero point zero two."
zero
As I use the long scale (based on powers of a million) as used in countries like Europe, I say it as: nine thousand billion (though some users of the long scale may say nine billiard).Others, however, use the short scale (based on powers of a thousand) as used in countries like USA and so say it as: nine quadrillion.Depending upon context I may also say it as: nine zero zero zero zero zero zero zero zero zero zero zero zero zero zero zero.
You would say 0.00006 as "zero point zero zero zero zero six" in words.
Zero cats.
Ancient Greek philosophers and theologians debated the concept of zero and the meaning of nothingness. To them, zero may have been undefined. Contemporary mathematicians do not enter into such debates in their roles as mathematicians (which is not to say that some of them may not have night jobs as philisophers or theologians). To mathematicians, zero is very well defined and an important element of mathematics.
You can say, "five one-hundredths," or "five hundredths." You can also say "zero point zero five."
You would say zero for the zeros " so 0001 would be zero zero zero one; or 0015 would be zero zero fifteen and so on. Hope this helped
"zero point eight zero"
one point zero four zero zero six
one point zero zero zero three
