Rounding methods

Rounding methods are techniques used to adjust numbers to make them simpler or more manageable, often for ease of communication or calculation. Common methods include rounding to the nearest whole number, decimal, or significant figure. For example, rounding 4.6 to 5 or 3.1416 to 3.14. Different approaches are used depending on the context, such as always rounding up, down, or to the nearest value with ties rounding in a specific direction. These methods help ensure consistent, understandable, and appropriate levels of precision in numbers across various applications.
