Why does Excel automatically round numbers?

The decimal rounding feature is pleasing to many users, but it is not all-inclusive. The main purpose of Excel's automatic rounding is to display numbers with reasonable accuracy and ease of reading. This helps users work with numbers more easily and avoid confusion due to odd numbers or too many decimal places.

Excel has several default rounding rules, including:

1. Round up: If the 5th decimal place is 5 or greater, Excel will round the number up. For example, 3.4567 will be rounded to 3.457.
2. Round down: If the 5th decimal place is 4 or less, Excel rounds the number down. For example, 3.4564 will be rounded to 3.456.
3. Round up to even: If the 5th decimal place is 5 and the 6th decimal place is even, Excel will round the number up. For example, 3.4550 will be rounded to 3.456.
