Round any number to the nearest whole number.
How it works
Standard rounding is applied to the ones place: 4.4 rounds down to 4, while 4.5 rounds up to 5.
What this does not include
This rounds to a whole number specifically — for a different magnitude, see this site’s other rounding calculators (nearest ten, hundred, tenth, hundredth, and thousandth).

How are negative numbers exactly halfway between two integers rounded?
Following standard JavaScript rounding convention, -4.5 rounds to -4 (toward positive infinity), not -5 — a subtle but consistent rule worth knowing if you’re checking results against another tool.
Is this the same as truncating decimals?
No — truncating simply chops off everything after the decimal point regardless of its value; rounding considers whether that fractional part is closer to the number above or below.
Why would I need to round to a whole number specifically?
Whole numbers are required whenever a fractional result doesn’t make sense in context — like a count of people, items, or units that can’t be split.
