Rounding Numbers
Say you lot wanted to circular the number 838.274. Depending on which place value yous'll round to, the final result will vary. Rounding 838.274:
- Rounding to the nearest hundred is 800
- Rounding to the nearest ten is 840
- Rounding to the nearest one is 838
- Rounding to the nearest tenth is 838.3
- Rounding to the nearest hundredth is 838.27
Basic Rules of Rounding
When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:
- Identify which identify value you are rounding to. The smaller the identify value, the more than accurate the concluding result volition be.
- Look to the next smallest identify value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you lot'd wait at the ones identify.
- If the digit in the side by side smallest place value is less than 5 (0, 1, 2, 3, or iv), you go out the digit you lot want to round to as-is. Whatsoever digits after that number (including the next smallest place value you lot just looked at) become zeros, or drop-off if they're located later the decimal point. This is called rounding down.
- If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits earlier the decimal bespeak become zeros, and any that are after the decimal point are dropped. This is called rounding upward.
New Content: Rounding Method of this Figurer
This Rounding Numbers Figurer uses the method called Round Half Away From Zero. An caption of this and other rounding methods can be found on our Rounding Methods Calculator page.
Rounding One-half Away From Nothing
Round halfway values away from nil. When the digit to the right is 5, this is the halfway value between rounding upwardly or downwardly. For the following examples let'southward round to the ones place for values betwixt 2 and 3 where the halfway point is two.5. In this method, whether y'all round a positive or a negative number, the accented value of the results are the aforementioned. Y'all can run into this symmetry effectually nix by comparing the positive and negative results. If your number to circular is negative yous tin can round the digits as you would for rounding a positive number.
For positive numbers:
Numbers less than the halfway point betwixt 2 and three, which is 2.5, round downward, toward 0. Numbers greater than or equal to the halfway point between ii and 3 circular up, away from 0.
- 2.four rounds down to 2
- two.48 rounds down to ii
- 2.5 rounds upwardly to three halfway, upward and away from 0
- two.52 rounds up to 3
- 2.6 rounds up to 3
For negative numbers:
Numbers greater than the halfway point between -three and -two, which is -2.v, round upwards, toward 0. Numbers less than or equal to the halfway bespeak of -2.five circular down, away from 0.
- -ii.iv rounds upwards to -ii
- -2.48 rounds up to -2
- -ii.5 rounds down to -three halfway, downwardly and abroad from 0
- -2.52 rounds down to -3
- -2.6 rounds down to -3
Round to the Nearest Hundred: 3250
- Identify the hundreds digit: the two in 3250
- Place the next smallest place value: the 5 in 3250
- Is that digit greater than or equal to v? Yes, and then round up.
- Increment the hundreds digit by 1, so 2 becomes three. Every digit after becomes a zippo.
3250 rounded to the nearest hundred is 3300
Round to the Nearest Ten: 323.v
- Identify the tens digit: the two in 323.5
- Identify the next smallest place value: the 3 in 323.five
- Is that digit greater than or equal to five? No, and so round downwardly.
- The tens digit stays the same at ii. Every digit after becomes a zero. Digits later the decimal indicate are dropped.
323.5 rounded to the nearest ten is 320
Round to the Nearest Ten: 499
- Identify the tens digit: the first ix in 499
- Identify the next smallest identify value: the 2d 9 in 499
- Is that digit greater than or equal to five? Yes, so round up.
- The tens digit increases past i. Since 9+ane=x, you lot need to carry the one and add together information technology to the digit in the hundreds place. Each digit after becomes a zero.
499 rounded to the nearest x is 500
Circular to the Nearest Tenth: 0.74
- Identify the tenths digit: 7 in 0.74
- Identify the side by side smallest place value: the 4 in 0.74
- Is that digit greater than or equal to five? No, so round down.
- The tenths digit stays the same at vii. Since the remaining digits are after the decimal betoken you just drib them.
0.74 rounded to the nearest 10th is 0.vii
Circular to the Nearest Hundredth: iii.141
- Identify the hundredths digit: the 4 in three.141
- Identify the next smallest place value: the second 1 in 3.141
- Is that digit greater than or equal to five? No, so round down.
- The hundredths digit stays the same at 4. Drop the digits to the right of 4.
iii.141 rounded to the nearest hundredth is 3.fourteen
