Identify the hundreds digit (third digit from the right). If it is 5 or greater, round the thousands digit up by 1 and replace all digits to the right with zeros. If it is 4 or less, keep the thousands digit as-is and replace all digits to the right with zeros. For example, 52,437 rounded to the nearest thousand is 52,000, and 52,537 becomes 53,000.
Look at the thousands digit (fourth digit from the right). If it is 5 or greater, round the ten-thousands digit up by 1; otherwise keep it the same. Replace all digits to the right with zeros. For example, 23,718 rounded to the nearest ten thousand is 20,000.
Check the ten-thousands digit (fifth digit from the right). If it is 5 or greater, round the hundred-thousands digit up; otherwise leave it unchanged, and set all lower digits to zero. For example, 271,403 rounded to the nearest hundred thousand is 300,000.
52,437 rounded to the nearest thousand is 52,000. The hundreds digit is 4, which is less than 5, so the thousands digit stays at 2 and everything to the right becomes zero.
23,718 rounded to the nearest ten thousand is 20,000. The thousands digit is 3, which is less than 5, so the ten-thousands digit stays at 2.
271,403 rounded to the nearest hundred thousand is 300,000. The ten-thousands digit is 7, which is 5 or greater, so the hundred-thousands digit rounds up from 2 to 3.
The most common mode is 'round to nearest', where .5 rounds up. 'Round half up' always rounds halfway values toward positive infinity. 'Round half down' rounds halfway values toward negative infinity. 'Ceiling' always rounds up to the next multiple regardless of the digit, and 'Floor' always rounds down. The differences only become visible at exact halfway points or with negative numbers.
Yes. Enter any negative number and the calculator applies the selected rounding mode correctly. For example, -52,437 rounded to the nearest thousand using the default mode is -52,000, while ceiling (round up) would give -52,000 and floor (round down) would give -53,000.
