What is Rounding to the Nearest Tenth?
Our round to the nearest tenth calculator helps you round decimal numbers to one decimal place. The nearest tenth refers to the first digit after the decimal point, representing tenths of a whole number.
When using a round to the nearest tenth calculator, you're essentially deciding whether to round up or down based on the hundredths place (second digit after the decimal).
Key Concepts:
- Tenths place: First digit after decimal
- Hundredths place: Second digit after decimal
- Round up if hundredths ≥ 5
- Round down if hundredths < 5
Essential Rounding Rules for the Round to the Nearest Tenth Calculator
Rule 1: Look at Hundredths
In any round to the nearest tenth calculator, examine the hundredths place (second decimal digit) to determine rounding direction.
Rule 2: 5 or Greater
When the hundredths digit is 5 or greater, round the tenths place up by one. This is the standard rule for most rounding scenarios.
Rule 3: Less Than 5
When the hundredths digit is less than 5, keep the tenths place unchanged. Simply remove all digits beyond the tenths place.
