Formatting Floats to Specified Decimal Places
When working with floating-point numbers, it is often necessary to format them to a specific number of decimal places. However, using the BigDecimal class may encounter precision issues.

String formattedFloat = String.format("%.nf", floatValue);
Benefits of this Approach:
- Provides a Float value, satisfying the requirement of a Float return type.
- Uses the String.format method, which ensures the number of decimal places specified in the format string.
- Avoids any potential precision issues with the BigDecimal class.
Example Usage
float floatValue = 625.3f; String formattedFloat = String.format("%.2f", floatValue); // outputs 625.30
