How Rounding Works

Rounding reduces a number to fewer decimal places while keeping its value close to the original. The standard rule: if the digit after the rounding position is 5 or greater, round up; otherwise, round down.

Common Rounding Scenarios

Rounding to the nearest whole number removes all decimals. Rounding to the nearest tenth keeps one decimal place. Financial calculations often round to the nearest hundredth (cent). Scientific measurements may round to various decimal places depending on precision requirements.
