Rounding to the Nearest Tenth Calculator
Batch process numbers to one decimal place. Features visual highlighting of the "determining digit" for educational purposes. Ideal for data cleaning.
About
Rounding to the nearest tenth (one decimal place) is a standard requirement in scientific reporting, grading systems, and financial approximations. The rule follows standard arithmetic rounding: if the hundredths digit is 5, 6, 7, 8, or 9, the tenths digit increments by one. Otherwise, it remains unchanged.
This tool distinguishes itself by offering Batch Processing. Users can paste a column of raw data from CSVs or Excel, and the tool will return a clean list. It also includes a "Visual Mode" that highlights the specific digit responsible for the rounding decision, making it an excellent teaching aid.

Reference Data
| Input | Looking at (Hundredths) | Action | Result |
|---|---|---|---|
| 4.23 | 3 (< 5) | Round Down | 4.2 |
| 4.25 | 5 (≥ 5) | Round Up | 4.3 |
| 4.29 | 9 (≥ 5) | Round Up | 4.3 |
| 9.96 | 6 (≥ 5) | Round Up (Carry over) | 10.0 |
