About Rounding Numbers

Rounding is a process used to reduce the number of digits in a number while maintaining its value close to what it was. The result is less precise but easier to use.

Common Rounding Rules
  • Round Half Up: If the digit to be removed is 5 or greater, round up. Otherwise, round down.
  • Round Half Down: If the digit to be removed is strictly greater than 5, round up. Otherwise, round down.
  • Round Half Even (Banker's Rounding): If the digit to be removed is 5, round to the nearest even digit. This method is statistically more accurate for large data sets.
  • Ceiling: Always round up, regardless of the digit's value.
  • Floor: Always round down, regardless of the digit's value.
  • Truncation: Simply remove digits without rounding.
Applications of Rounding

Rounding is used in many fields:

  • Financial calculations and accounting
  • Statistical analysis and data reporting
  • Scientific measurements and experiments
  • Computer science for memory optimisation
  • Everyday calculations for simplicity
