The headline is stored to 9 decimals, as published.
Rounded by this site
Never. Tables on screen may show fewer decimals; the files never do.
Changed by this site
Reshaped into one row per country: regional and income-group totals are left out, only the columns listed are kept, each row gets its ISO 3166 code, and some country names are brought to one spelling. No value is recalculated, rescaled or rounded.
From the 2025 Human Development Report, which recalculates every year at once on one current method.
