You don't round 0 because it's already a whole number (an integer) and the base for rounding, but if you're rounding a number near zero, like 0.4, you round down to 0, and if you're rounding 0.5 or greater, you round up to 1 (usually), depending on the specific rounding method used, though rounding 0.5 to 0 or 1 depends on the rule.
Following the old rules, you can round a number down in value four times (rounding with one, two, three, four) compared to rounding it upwards five times (five, six, seven, eight, nine). Remember that "rounding off" a zero does not change the value of the number being rounded off.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), leave the digit you want to round to as-is. Any digits after that number become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
Rounding towards zero is the simplest rounding mode computationally. All digits beyond the number required are dropped. Rounding towards zero results in a number whose magnitude is always less than or equal to the more precise original value.
Zero does not exist in the sense that a physical object does. It does exist as a word, a symbol, a mathematical concept and a common idea. I suggest that zero is a cognitive crutch, a way for humans to grasp the concept of absence, but not an objective existence in itself.
First, it's easier to remember that 0.5... always goes up, because anything other than infinite zeroes after that 5 is closer to the up number than the down number. "Round 5-9 up unless it's exactly on 0.5" is just an extra exception to learn that doesn't need to be there.
To round 37 to the nearest hundred, we look at the digit in the tens place. This digit is 3, which is between 0 and 4, and so 37 should be rounded down to 0. This also means that on a number line, 37 is closer to 0 than to 100.
Round 3.84 to the nearest ones:
The digit in the ones place is 3. The digit to the right (tenths place) is 8, which is greater than 5. Therefore, we round up from 3 to 4.
It is exactly halfway between 0 and 1, so it is not closer to 1... nor is it closer to 0. It is exactly halfway between them. The same principle applies to other things like 11.5 or 23.5.
Since 0.7 has a larger digit in the tenths place, 0.7 is greater than 0.07.
Whenever the fractional part is 0.5, alternate rounding up or down: for the first occurrence of a 0.5 fractional part, round up, for the second occurrence, round down, and so on.
Rules for rounding decimals:
Look at the digit to the right of the number being rounded. If that digit is 4 or less, change that number and all the numbers after it to zeros. If that digit is 5 or more, increase the number being rounded by 1, and then change all the numbers after it to zeros.
Answer and Explanation:
The number 983.491 rounded to the nearest whole number is 983. Your choices for rounding 983.491 would be to round it down to 983 or up to 984, since the number 983.491 falls between 983 and 984 on the number line.

50 is exactly half-way between 0 and 100. 32 rounds down to 0 because it is closer to 0 than 100 on the number line. 50 is exactly half-way between 0 and 100. 79 rounds up to 100 because it is closer to 100 than 0 on the number line.
Rounding to Even is rooted in a standard called IEC 60559. The standard dictates that you round to the nearest even number. So, round(0.5) becomes 0 and even round(-1.5) becomes -2.
The exception is when the decimal is smack dab between two integers: 4.5 is exactly equidistant to both 4 and 5, but because of the “tie-breaker” rule of rounding, anything with a 5 in the tenths digit is rounded up. This is the only case in which the “go to the closer integer” interpretation will fail.
8.9 rounded to the nearest integer is 9.
In mathematics, the symbol ∅ represents the empty set, which is a set containing no elements at all. It is also commonly referred to as the null set and is a fundamental concept in set theory as it serves as the unique set with zero members.
0× 0 × ____ =1 = 1 . There is no such number. We cannot find it because it doesn't exist. Since it doesn't exist, zero does not have a reciprocal, so dividing by 0 will not work.
