N'ihe banyere calculator a

A rounding calculator rounds a number to a chosen number of decimal places (or significant figures) and shows four results side by side: the standard nearest-value rounding, always-up (ceiling), always-down (floor), and truncation, so you can compare every option at once.

Standard rounding looks at the digit just past the cut-off — 5 or more rounds up, less than 5 rounds down — so 3.14159 to two decimal places is 3.14. The other columns force a direction: for 2.673 the nearest and floor both give 2.67 while the ceiling gives 2.68, and truncation simply drops the extra digits to 2.67 without rounding. Switching the mode to significant figures counts meaningful digits from the first non-zero one instead, and a negative number of places rounds to the left of the point, so 3457 to −2 places becomes 3500.

Rounding matters for money, measurements, reporting to a sensible precision, and avoiding false accuracy in results. Seeing nearest, up, down and truncated together makes it clear how much a value shifts depending on which rule you apply.
