- Rounding 1234.567 to the nearest thousand using "round half away from zero".
- The rounding step is 1000, so the neighbours are 1000 and 2000.
- 1234.567 / 1000 = 1.234567, which the rule sends to 1.
- 1 x 1000 = 1000

What the round to nearest thousand calculator calculates
Rounds a number to a chosen number of decimal places, a named place value, the nearest multiple, or a number of significant figures, under any of the standard tie-breaking rules including half away from zero and banker's half-to-even, and estimates a sum by rounding every addend to a place value before adding them.
How to use this round to nearest thousand calculator
Enter Number to round and Tie-breaking / direction rule. Rounded value updates as you type. Change one figure at a time to see what drives the result.
How the result is worked out
Open “How this is worked out” beside the result for the step-by-step calculation behind Rounded value, Rounded value (formatted) and Rounded minus original.
The method follows IEEE Std 754-2019, Standard for Floating-Point Arithmetic, §4.3 Rounding-direction attributes (roundTiesToEven, roundTowardZero, roundTowardPositive, roundTowardNegative) and NIST Special Publication 811, Guide for the Use of the International System of Units, Appendix B.7 "Rounding converted numerical values".
What you can compare
Change one input at a time to see how it affects Rounded value, Rounded value (formatted) and Rounded minus original. The inputs you can vary are Number to round and Tie-breaking / direction rule.
