How to Format a Float to N Decimal Places in Java?

Format Float to n Decimal Places with String Format

To format a float to a specified number of decimal places, consider using the String.format() method instead of BigDecimal:

<code class="java">import java.lang.Math;

public static float Redondear(float pNumero, int pCantidadDecimales) {
    //Round the float value and convert it to a string with specified decimal places
    String roundedValue = String.format("%.2f", pNumero);
    
    //Parse the string back to a float to maintain float precision
    return Float.parseFloat(roundedValue);
}</code>

Example:

<code class="java">float originalValue = 625.3f;
int decimalPlaces = 2;

float roundedValue = Redondear(originalValue, decimalPlaces);
System.out.println("Rounded Value: " + roundedValue); // Output: 625.30</code>
