About this tool
This page opens the rounding calculator locked onto the whole-number place, so any decimal you enter comes back as a plain integer with a short explanation of why it went up or down.
Only the tenths digit decides. 7.5 rounds up to 8 because the deciding digit is exactly 5, and 7.49 rounds down to 7 because the deciding digit is 4 — the 9 after it changes nothing. That second example is the classic classroom trap: rounding in two steps (7.49 to 7.5, then 7.5 to 8) is simply wrong, and the explanation line under the result shows the single digit that legitimately made the call.
Negative numbers follow the same digit rules with the sign kept intact: −2.5 becomes −3 under half up, −2 under banker's half even, −3 under floor and −2 under ceiling. Try the four modes to see how each convention treats the same input — everything is computed locally in your browser.
Example. Half-up rounding of 2.675 to the hundredth returns 2.68.
Limit. Place values run only from the millions place down to the ten-thousandths place.
