rounding unit - Should I round a decimal number of people up or …
2018年12月19日 · Instead, it is at best approximate. Whether that means in any specific case rounding up, down, to the nearest integer, or even making a larger adjustment, is not clear. In many cases, the assumption will be to either round down or to the nearest integer, but always rounding up is also a fairly reasonable thing to assume.
arithmetic - Rules for rounding (positive and negative numbers ...
$\begingroup$ Re: bias, that's the reason for the "banker's rounding" (round to nearest even) strategy; when you're faced with only (or at least primarily) positive numbers, the "away from zero" bias can add up over time. "Round to nearest even" avoids introducing bias even if all your values are positive, as long as they're distributed equally ...
numerical methods - How do you mathematically round a number ...
For floor rounding we eliminate the decimal part by subtracting the decimal part of the divided number from the divided results. For ceiling rounding we figure out the number that, when added to the divided results, will increase it to the next whole number.
Why do we generally round 5's up instead of down?
2013年3月5日 · WE do this because when you round, generally it is with decimals that are rational or long. When there is 5.000000000000000001, it is better to round up. So, lets say you have the square root of 26 (5.09901951359) It's close to 6 than to 4. When rounding, you can't have 5.090919534243123 whatever to round down because decimals cant go down.

2017年8月15日 · Like lets say 412 to 425 or 400 (if the multiples are 25) or 516 to 550 or 500 (if the multiples are 50). I don't know this is not rounding but how would this go?
Rounding vs Approximating - Mathematics Stack Exchange
2017年7月20日 · Rounding is to take the nearest number with a given number of digits. To approximate is to give any number nearby, not necessarily with a finite number of digits. For example, x =2.4564 is rounded to 2.46 with two decimal places, and $\frac {211} {90} = 2.455555...$ is an approximation of x within 0.2%.

I'm stuck with rounding decimals and have been for years
2014年4月1日 · $\begingroup$ @JérémyBlanc There are many different conventions for what to do when rounding from an exact midpoint value - I would say that the most 'common', particularly in computer sciences, is to round so as to make the last digit even - so 8.645 would round to 8.64, while 8.655 would round to 8.66. $\endgroup$
rounding up to two decimal points - Mathematics Stack Exchange
2018年3月21日 · This is about what counts as a decimal point or not. $2.89$ is clearly three significant figures, but to me that's two decimals (digits after the point). The only thing that will help you here is to actually discuss this with your teacher and find out how he / she defines it.
