Rounding replaces a number with a simpler approximation. The most common method is round-half-up: if the digit after the rounding position is 5 or greater, round up; otherwise round down.

Пошаговое руководство

  1. 1Identify the place value you are rounding to (ones, tens, tenths, etc.)
  2. 2Look at the digit immediately to the right
  3. 3If it is 5 or more, add 1 to the rounding digit and drop everything to the right
  4. 4If it is 4 or less, keep the rounding digit and drop everything to the right
