Answer: The default setting is no zeros are automatically added to the right of a decimal point. You need to set the format of the cell if you want a specific numbe of places to display to the right of the decimal point.
Answer: In Excel, the default format is called "General".
General format is the default setting for most excel releases. Occasionally one may have an accounting format as default depending on software release.
Yes it does.
number, decimal = 0
Only in numbers containing decimal points.
three, leading zeros are not significant and trailing zeros are significant if there is a decimal. trailing zeros are not significant if there is no decimal zeros in the middle of numbers are significant
Leading zeros and trailing zeros in numbers that don't have a decimal point.
There are 90,000,000 whole numbers.If you include negative numbers, this doubles to 180,000,000.If you include decimal numbers, eg 1.2345678, there are 666,000,000 positive numbers, disallowing numbers with extraneous 0's.Including negative numbers, this doubles to 1,332,000,000If you allow trailing 0's in the decimal place, than this becomes 730,000,000 non-negative numbers, or 1,459,999,999 numbers (since -0.0000000 = 0.0000000)If you allow a decimal point without a digit in front, there are a further 90,000,000 non-negative numbers, or 180,000,000 including negative numbers.Allowing trailing 0's, this becomes 100,000,000 non-negative or 199,999,999 numbers.Maximum total:1,659,999,998 allowing trailing 0's, and allowing numbers without a digit in front of the decimal point.
To multiply decimal numbers, the decimal point is ignored and the multiplication is done as though they were (large) integers. The last step is to put the decimal point into the answer by ensuring the same number of digits follow it as were following the decimal points in the numbers multiplied together; trailing zeros can be removed at this point.
It is 400. Decimal refers to a way of representing numbers in which the place value of each digit is ten times the place value of the digit to its right. Decimal does not require a decimal point nor trailing zeros.
If two decimal number have X and Y decimal places, respectively, then the raw product (before removing any trailing zeros) of the two numbers will have (X + Y) decimal places.
If the two numbers have x and y decimal places respectively, then the raw product (before deleting and trailing 0s) has (x + y) digits after the decimal point.
The commutative property of addition applies to all real and complex numbers. It has nothing whatsoever to do with the form in which the number is represented: decimal, binary, etc.
My Chemistry teacher defined trailing zero's as the ones that follow another number. We used them in relation to significant figures. If that's how you're using them (as significant figures) then the numbers are sometimes significant. If they come after a decimal point they're significant. Like 300.0 the 2 zero's before the decimal point are unsignificant, and the one after is (It's also a trailing zero).
Significant numbers by definition do not include leading or trailing zeros which merely serve to show the scale of a number. Thus 83,000 and 83,000,000 and 830 all have the same number of significant numbers, 2. The two significant numbers are 8 and 3. * * * * * Clarification: Trailing 0s AFTER the decimal point DO count unless they are there purely for conventional reasons (for example, two decimal places in most currencies). Such trailing 0s are indications of the precision of the number. So, for example, 0.83 has 2 significant figures but 0.830 and 8.30 have 3 while 8.300 or 0.00008300 have 4.
