only one zero can be added using a decimal
yes if you want to check the percentage of something or if you want a decimal
0.0000000000000000000000000000000000001 is a very small decimal number. ^^
There is a button entitled "increase decimal". Its location depends on the version of Excel you are using.First you must select the cell/s you wish to alter and then press the "increase decimal" button.In Excel 2003 it is on the Formatting toolbar. It has the appearance of a small blue arrow, pointing left and is followed by a decimal point and single zero, overlying a decimal point and a double zero and looks roughly like the following:← .0.00In Excel 2007 the button can be found in the following location: On the Home tab, in the Number group.Please see related links.
0.0001
9 can be divisible by 90, though it would be an incredibly small decimal. If you're asking if 9 can be divided by 90 and get a whole number, then no, it cannot. If you accidentally wrote 90, but meant only 9, then yes, 9 can be divided by 9, and get 1
No not quite that small because its value is nearly equal to a whole number of 1
There is no such number as "the smallest decimal".Any number you give me, no matter how small, I can always give you back a different numberthat's smaller than yours.
if not going to the number 1 there is infinit here is a big (rather small) decimal 0.99999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999 etc. 8
That is not what mathematicians mean by an irrational number, which is a number with an infinitely long decimal expansion. You will note that since division is the inverse of multiplication, dividing by small numbers has the same effect as multiplying by large numbers, and so dividing by zero, which is an infinitely small number, is equivalent to multiplying by infinity. The result in most cases is deemed to have no mathematical meaning.
A repeating decimal is any rational number whose decimal representation does not terminate after a given number of digits. As only a very small quantity of the rational numbers terminate in their decimal representation, practically any rational number picked at random will be a repeating decimal.
As many as required: there is no limit.
Scientific notation is used to express very large or very small numbers. instead of writing 15,000,000, you can express the same number by writing it as 1.5 * 107 or, you could express the very small number .00000015 as 1.5 * 10-7 to express a number in scientific notation, simply place a decimal point after the first number (in a large number) or before the last number (in a very small number) and multiply by ten to the nth power, where n is the number of digits following the decimal point (in a large number) or negate the number of digits before the decimal (in a very small number).
