About Rounding
Rounding is the process of reducing the number of significant digits in a number while keeping its value close to the original. This is useful for simplifying calculations, displaying results, and working with approximate values.
Common Applications:
- • Financial calculations and currency
- • Scientific measurements and data
- • Statistical analysis and reporting
- • Engineering and technical specifications
- • Everyday calculations and estimates
Rounding Rules:
When rounding, if the digit to the right of the rounding position is 5 or greater, round up. If it's less than 5, round down. For exact halves, round to the nearest even number (banker's rounding).
