Round to the Nearest Hundredth Calculator
Enter any number and instantly see it rounded to the nearest hundredth (0.01), with the bounding hundredths shown on a number line.
Your number rounded to 2 decimal places (nearest 0.01)
- 1
Shift decimal two places right
3.14159 × 100 = 314.159 - 2
Round to nearest integer
round(314.159) = 314 - 3
Restore decimal (÷ 100)
314 ÷ 100 = 3.14
How does this calculator work?
Multiply by 100, round to the nearest integer (half-up), divide by 100. For 3.14159: 314.159 → 314 → 3.14. For 3.145: 314.5 → 315 → 3.15. The result always has at most 2 decimal places and differs from the original by no more than 0.005.
Formula
How this is calculated
Rounding to the nearest hundredth means keeping exactly two decimal places. The method multiplies your number by 100 (shifting the decimal two places right), applies standard half-up rounding to get the nearest whole number, then divides by 100 to restore the scale. For example, 3.14159 × 100 = 314.159 rounds to 314, giving 3.14. For 3.145, 314.5 rounds to 315, giving 3.15.
The rounding error is the absolute difference between the original value and the rounded result; it is always at most 0.005 (half a hundredth). The number line shows your original value positioned between the bounding hundredths, making it visually clear which way the rounding went.
One important caveat: because computers store decimals in binary floating-point, a small number of values near the exact midpoint can round in an unexpected direction due to representation limits. For example, 2.675 may be stored internally as 2.6749999…, causing it to round down to 2.67 rather than up to 2.68. This is a floating-point artefact, not a flaw in the rounding rule itself.
Frequently asked questions
3.14159 rounded to the nearest hundredth is 3.14, because the third decimal digit (1) is less than 5, so the second decimal place stays at 4.
3.145 rounded to the nearest hundredth is 3.15 with half-up rounding. The third decimal digit (5) meets the threshold, so the second decimal rounds up from 4 to 5.
Yes — one hundredth is 1/100 = 0.01, so "nearest hundredth" and "two decimal places" are exactly the same operation.
