Round to the Nearest Hundredth
Rounding to the nearest hundredth keeps two decimal places: pi, 3.14159…, becomes 3.14, and 2.71828 becomes 2.72. Hundredths are the precision of money (the hundredth is the cent), of percentages quoted to two places, and of stopwatch times in sprint races where a hundredth of a second separates medals. All values on this page use standard half-up rounding.

How to use the Round to the Nearest Hundredth
- Check Number to round: 3.14159.
- Check Round to: places.
- Check Decimal places: 2.
- Review the Round to the Nearest Hundredth result and its exact-value comparison table.
- Verify assumptions before applying the result.
Formula
Round half up at the chosen precision: decimal places count digits after the point, significant figures count digits that carry meaning from the first nonzero digit, and nearest-multiple rounding snaps to a grid such as the nearest 100.

Frequently asked questions
Rounding to the nearest hundredth keeps two decimal places: pi, 3.14159…, becomes 3.14, and 2.71828 becomes 2.72. The reference table on this page shows 8 worked examples computed with exactly that rule.
A third decimal of exactly 5 is the tie — 0.005 rounds up to 0.01 on this page. Because decimals are stored in binary, a typed 3.145 is held a hair below the exact tie and shows 3.14 here; decimal-string rounding would give 3.15, and some scientific conventions use banker's rounding (half-to-even) at ties instead.
Use it for currency conversions, percentage results, exam scores and any decimal that will be printed in a report or table.
0.004 rounds to 0. You can verify it in the table on this page, or type any other value into the calculator above.
In sprint finals, where Olympic timing resolves to the hundredth and gold and silver are routinely separated by one or two of them — and in money, where interest rates and APY are quoted to the hundredth of a percent because 4.25% and 4.26% are genuinely different offers over a 30-year loan. Hundredths are where 'approximately' stops being good enough.
No. Banker's rounding (round-half-to-even) is used in some scientific and financial standards to reduce bias over huge datasets, but this page — and the parent rounding calculator — always rounds a halfway value up, which is the convention taught in schools and used for tax forms.
Yes, with one nuance: the engine rounds halves toward positive infinity, so 47.5 rounds up to 48 at the nearest dollar while -47.5 becomes -47. Away from exact halves, negative values round to the nearest candidate just like positive ones.
