If you're searching for how to round to the nearest hundredth, this calculator is what you need. Input the number to round, and the calculator will do its job.

The calculator uses, by default, the half up rounding mode, the one used most of the time in math. Even so, if you click on the advanced mode, you can change it.

Keep reading this article to learn more about rounding to the nearest hundredth, or look at the FAQ section, where you'll see 2.85 rounded to the nearest hundredth and other similar questions.

💡 In the lower part of the calculator, you can look at many examples of rounding to the nearest hundredth, which will vary depending on the rounding mode you choose.

How to round to the nearest hundredth (and an example)

Rounding to the nearest hundredth means truncating a decimal number at the hundredth position. The hundredth position corresponds to the second digit located to the right of the decimal point. Therefore, rounding to the nearest hundredth means keeping a precision of two decimals.

Let's learn, through an example, how to round to the nearest hundredth by rounding 1.625. Follow these steps:

  1. Identify the digit at the hundredth position (always the second digit after the decimal point).
    • In this case, that digit is 2.
  2. Identify the digit to the right of the hundredth digit.
    • In this case, it is 5.
  3. If the digit to the right of the hundredth digit is 5 or greater, we round up the hundredth digit; otherwise, we leave it as it is.
    • In this case, 2 rounds up to 3 because the digit to the right equals 5. Therefore, 1.625 rounded to the nearest hundredth is 1.63.
    Additionally, if the number to round (the second decimal) is 9, we change it to zero and increase the first decimal by one unit. E.g., $4.0962 ≈ $4.10 and 7.2951 ≈ 7.30. If the first decimal is also 9, we do the same for it: $4.9962 ≈ $5.00 and 7.9951 ≈ 8.00.

If you want to learn about the other rounding modes, you can look at our rounding calculator, where you can see how the up, down, ceiling, floor, and the different rounding modes work.

💡 You don't need rounding if the number has fewer than two decimal digits, as there is no thousandth!

However, you can pad the number with trailing zeros (e.g., 3 → 3.00). Nevertheless, depending on the situation, those additional zeros could create false precision, as they could not represent true significant figures. Look at the significant figures Wikipedia article to learn how they relate to trailing zeros.

FAQ
