Rounding Calculator

Enter a number to be rounded off and the calculator will instantly round it off to the nearest tenths, hundredths, thousandths, or higher precision.

The rounding calculator helps to round numbers up or down to the nearest ones, tenths, hundredths, thousandths, ten thousand, hundred thousand, etc. In simple terms, this rounding numbers calculator allows to round numbers up or down to any decimal place.

What Are You Rounding to?

While rounding off number, the very first thing to observe is that: what are you rounding it to? Figures can be rounded to the close ten, hundred, thousand, and so on. Example: If you have a number 4,827 then it can be rounding off as follow:

  • It's rounding to the nearest tenth will be: 4,830
  • 4,827 will be round to the nearest hundred: 4,800
  • round to the nearest thousands of 4827 will be: 5,000

Rounded table of numbers:

Name of the rounding Corresponding number Number before (+), after (-1) the comma
Million 1 000 000 7
Hundred thousand 100 000 6
Ten thousand 10 000 5
Thousand 1 000 4
Hundred 100 3
Ten 10 2
Unit 1 1
Tenth 0,1 -1
Hundredth 0,01 -2
Thousandth 0,001 -3
Ten thousandth 0,0001 -4
Hundred thousandth 0,00001 -5
Millionth 0,000001 -6

Rounding Numbers To The Nearest Tenth:

The more realistic way to understand this method id to observe the number line before rounding off your numbers. Under this strategy, if the unit of the given number is smaller than five, then you will follow the “round down” rule. If the given number is greater than 5, then “round-up” will be applicable.

Rounding Numbers To The Nearest Hundred:

If the tens digit in the given number is lesser than 50 then you will apply the “round down” rule but if the tens digit is 50 or greatest then 50, round up will be applied. For example, if you have a number 834 then the ten is “34” that is less than 50 so you will round down the number to 800. In the same way in the case of 871, the tense is “71” that is greater than 50, so the number will be transformed into 900.

Rounding Numbers To The Nearest Thousand:

Sometimes you need to round four-digit numbers to the nearest ten, hundred or thousand. For example:

  • If the given number is 2431 and you have to round off to the nearest ten, then it will be 4230.

But if you have to round off to the nearest 1000 then your hundred will be observed; if it is less than 50 then you will round down and if it is greater than 50 you will round up the number. For example:

  • If the given number is 2839 the “83” is greater than 50 so the number will be round up into 3000.

Round To The Nearest Hundredth:

While round to the nearest cent, nearest penny, or nearest hundredth, the same procedure will be applied. All you have you to do is to look for the hundredths place. After locating the 100th place look at the digit to the right side. If this digit is 5 or greater than 5, the number in the 100th place will be increased by 1. All those numbers that are present after it will be simply dropped.

Rounding Numbers To The Nearest Thousandth:

Round to the nearest thousandth: 34.4317

  • First, figure out the thousandths digit: 1 in 34.4317
  • Now, find the smallest place value: 7 in 34.4317
  • You can see that digit is greater than five, so round off
  • So, 1 + 1 = 2
  • 34.4317 rounded to the nearest thousandth is 34.432

Rounding Numbers To The Nearest Ten:

Rounding to the nearest ten: 434.2:

  • Simply, identify the tens digit: the 3 in 434.2
  • Right after, you just have to figure out the next smallest place value: the 4 in 434.2
  • Take a look, is that digit greater than or equal to five? No, it’s not, so simply round down
  • The tens digits will remain the same at 3 and every digit after turns a zero. Here, the digits after the decimal point are dropped
  • 434.2 rounded to the nearest ten is 430
