### Rounding Numbers

Wondering what rounding a number is? Let us show you a simple example. For instance, you need to round the number 546.263. Now, depending on the place value you intend to round up this digit to, the results will be:

- 500 to the nearest hundred
- 540 to the nearest ten
- 546 to the nearest one
- 546.3 to the nearest tenth
- 546.26 to the nearest hundredth.

### General rules or rounding

Rounding a number means creating a number that has about the same value as the starting one but is less exact. It is a simple process that can be done in just a few steps:

- Decide what place value you are rounding to – the nearest thousand, hundred, ten, one, tenth, etc. Just remember: the higher the value, the less accurate the result.
- Check what the digit in the next smallest place value is. If you, for instance, want to round to the nearest ten, you need to look at the ones.

If the next digit is less than 5 – 0, 1, 2, 3, or 4 – you round down the number. This means leaving the digit you want to round as is.

If, however, the next place value is 5 or higher – 5, 6, 7, 8, or 9 –you round up the number. Meaning you increase the number or the digit by one.

### Rounding methods

There is a variety of rounding methods used in math. In the default mode, our calculating app rounds to the nearest number. However, you can switch up the settings and use other modes that match your needs. Our service covers the eight most popular rounding methods. However, if you need some other tool, feel free to tell us, and we'll add it to our roster.

**Rounding half up.**This is a popular method for rounding numbers. The calculator rounds half the number up, giving the most accurate results. Half 0.5 of the number increases to the decimal value. For instance, if you need to round up a number 7.50, the nearest result will be 8.

**Rounding half down.**The other common rounding method is rounding half down. This basically means decreasing the integer 0.5 to the decimal. Say, you need to round down the number 7.50. In this case, the nearest digit will be 6.

**Rounding up.**When you use an online calculating app to round up the number, you increase it to the next highest value. According to the rounding rules, you can round up the number when its value follows the digits 5, 6, 7, 8, 9. So, if you need to round up 6.5, your result will be 7.

**Rounding down.**Rounding down a number means decreasing it to the nearest value. It can take place when your number is less than five (the next digit is 0, 1, 2, 3, or 4). So, if you were to round down the number 6.4, the result would be 6.

**Rounding half to even.**Unlike other methods, rounding half to even is free from biases toward or away from zero as well as positive or negative biases. Thus, it can be regarded as a tie-breaking rule. When using this approach, you round half value to the next even integer. For instance, 5.5 rounds up to 6, as well as 6.5.

**Rounding half to odd.**Similar to rounding half to even, half to odd rounding is a tie-breaking rule of its kind. As a rule, numbers are rounded up to the next odd integer. For example, 5.5 becomes 5, while 6.5 becomes 7.

**Rounding half away from zero.**As in the two previous approaches, rounding half away from zero does not possess positive/negative biases but has a bias away from zero. It means rounding half values towards the nearest integer that is further from zero or closer to infinity (positive or negative, depending on the value). So, 5.5 becomes 6, while -5.5 is rounded to -6.

**Rounding half toward zero.**This approach is similar to rounding half away from zero, as it has only a bias towards zero. For this method, a number is rounded to the next integer that is closer to zero compared to its positive/negative infinity. So, in this case, 5.5 rounds up to 5 and -5.5 – to -5.

## Frequently Asked Questions

### Why do we need rounding?

Rounding is a great way to facilitate your calculations and make the numbers more understandable. It also allows you to create numbers that are close to the original value and have the initial meaning. With our efficient tool, you can round to the nearest hundred/ten/tenth/hundredth without worrying about preciseness. So, if you need 100% correct results, use our free calculator to round numbers.

### How to round a number to the closest integer?

When rounding numbers to the nearest integer, you have to follow these rules:

- Round down when the nearest digit is 0, 2, 3, or 4. Just remove all numbers after the decimal and keep the other part intact.
- Round up if the closet number is 5, 6, 7, 8, or 9. Delete all the digits after the decimal and increase the part before it by one.

### What is a rounding calculator?

To correctly display the results, every calculator has to round numbers. Furthermore, if not rounded, calculations that result in irrational numbers would go on infinitely unless they are programmed otherwise.

A round calculator, however, is a tool that helps to round numbers to the nearest result accurately and promptly. It replaces the initial number with the nearest version, which is shorter and more explicit. For instance, the number 6.7 would be rounded to 7.
