📝 Explanation:

When we work with floating-point numbers in JavaScript, results can sometimes include extra zeros after the decimal point.

For example:

5.500 → 5.5

10.00 → 10

7.123400 → 7.1234

The goal is to round the number to the desired decimal place and then remove extra zeros at the end.

This ensures your output looks neat and professional, without confusing users with irrelevant digits.

Common uses include:

Currency formatting (e.g., 19.90 → 19.9, 20.00 → 20)

Scientific results where precision matters, but extra zeros don’t add meaning

User interfaces where numbers should look simple and clean
