Rounding Error
Rounding error occurs when a number is approximated to make it simpler to work with, leading to a small difference between the actual value and the rounded value. This is common in calculations involving decimals, where numbers are rounded to a certain number of digits, such as rounding 3.14159 to 3.14.
These errors can accumulate in larger calculations, potentially affecting the final result. For example, if multiple rounded numbers are added together, the total may be slightly off from the true sum. Understanding rounding error is important in fields like mathematics and computer science to ensure accuracy in results.
