How to Round a Float to a Specific Number of Decimal Places in Java?

Rounding a Float with Precision

The task at hand requires formatting a float to a specified number of decimal places. While BigDecimal is a viable option, its return value may not align with expectations.

To achieve the desired outcome, a more straightforward approach can be employed. Float.toString() provides a simple solution:

<code class="java">public static float formatFloat(float value, int decimalPlaces) {
    return Float.parseFloat(String.format("%.2f", value));
}</code>

By utilizing this method, we pass the float value and the desired number of decimal places as parameters. The String.format function is then invoked to create a formatted string with the specified precision. Finally, the formatted string is parsed back to a float, ensuring that we obtain a float value with the intended decimal precision.
