How do you compute rounded numbers?

Simply to look at the number and ask "what is the nearest 1000", or, "what is the nearest whole number? etc" Or follow the rules: Basically divide by (say,) 1000) add 1 if the decimal part is 0,5 or greater, and discard the decimal bit ("rounding"), and multiply back by the original divisor. So for example 658879 -> 658.879 -> 659 -> 659000 has been "rounded to the nearest 1000". Quite often people want to round to the nearest whole number, which simply means ignore the decimal bit if less than 0.5 , or add 1 unit if greater than 0.5 the throw away the decimal bits, for example 34.6 -> 35 . That's actually the same route as the first example, but of course multiplying by 1 first etc is a waste of time.

The rounded value is 10. See also the links below. * * * * * However, there is no such thing as the correct number of significant figures (sf). SF depends on the context as well as the SF of the numbers used to compute the value.


What is a sentence using the word compute?

It is possible to compute numbers larger than can be written using normal mathematics. There is an algorithm that is used to compute the decimal expansion of pi. It is easy to compute the sum of all the counting numbers from one to 100. Add the highest and lowest, and you will get 101. Add the next highest, 99, and the next lowest, two, and you will again get 101. If you continue in this way to compute the sums, you will have the sum 101, computed 50 times. Now compute the product of 50 and 101, and you will get 5050. This is the sum of all the counting numbers from one to 100.
