The value of pi, to its first four decimal places. Pi cannot be written in full as a decimal number, so it is impossible to write it in full. As a result it is usually rounded up or written with the first few of its decimal places, as in this case.

It is 1017.9The two numbers, rounded to 1 decimal place on either side of 1017.87 are 1017.8 and 1017.9 Of these the latter is closer and so the result.
Three decimal places.A simple rule of thumb for multiplying decimals; ignore the decimals and just multiply the number together.0.111 x 0.1; would become 111 x 1 = 111Then count all the numbers after the decimal. 0.111 (3) and 0.1 (1) 3+1=4And put the decimal point that many places from the right.With four places 111 becomes:11.1 ( one place)1.11 (two places)0.111 (three places)0.0111 (four places)0.111 x 0.1 = 0.0111----------------------------There is 2 decimals digits in hundredths and 1 decimal digit in tenths, thus when multiplied together they will have 2 + 1 = 3 decimal digits.However, if the decimal digits on the right hand end are zero they are not written, and less than 3 can be written.Examples:0.97 × 0.3 = 0.2910.17 × 0.3 = 0.0510.12 × 0.5 = 0.060 = 0.06When multiplying decimal numbers, multiply them without the decimal point and then put the decimal point back in to the result by counting the total number of digits after the decimal points in the original numbers and ensuring that the same number are in the result.Thus as the first number has 2 decimal places and the second that 1 decimal place, the result will have 1 + 2 = 3 decimal places.
The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". 13.55 (2dp) can be obtained from numbers with 3 decimal places ranging from 13.545 to 13.554. Six possibilities for the original number are 13.545, 13.547, 13.549, 13.551, 13.552, 13.554. NOTE : If the choice of original numbers were extended to numbers having (say) 6 decimal places of figures then the six possible numbers could have been chosen from the range 13.545001 to 13.554999

No - 17 is not the result of cubing an integer - its cube root, rounded to nine decimal places, is equal to 2.571281591.

The result of dividing 115 by 6 is 19.1667 when rounded to four decimal places.
= significant figures = and got For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places.
This function has to do with the format of a cell and how many decimal places are shown. Applies only to numbers. Keep in mind that the actuall value is unchanged. For example, the number will be rounded if you specify 0 decimal places.
Yes, but you can then change the amount of decimal places you see.

To change 710 to a decimal, divide it by 100. The result is 7.1. Rounding it to the nearest hundredth means keeping two decimal places, so the rounded decimal form of 710 is 7.10.
