BigInteger floatValue() Method in Java Last Updated : 04 Dec, 2018 Comments Improve Suggest changes Like Article Like Report The java.math.BigInteger.floatValue() converts this BigInteger to a float value. If the value returned by this function is too big for a magnitude to represent as a float then it will be converted to Float.NEGATIVE_INFINITY or Float.POSITIVE_INFINITY as appropriate. There is a chance that this conversion can lose information about the precision of the BigInteger value. Syntax: public float floatValue() Returns: The method returns a float value which represents float value for this BigInteger. Examples: Input: BigInteger1=32145 Output: 32145.0 Explanation: BigInteger1.floatValue()=32145.0. Input: BigInteger1=32145535361361525377 Output: 3.2145535E19 Explanation: BigInteger1.floatValue()=3.2145535E19. This BigInteger is too big for a magnitude to represent as a float then it will be converted to Float.NEGATIVE_INFINITY or Float.POSITIVE_INFINITY as appropriate. Below programs illustrate floatValue() method of BigInteger class: Example 1: Java // Java program to demonstrate floatValue() method of BigInteger import java.math.BigInteger; public class GFG { public static void main(String[] args) { // Creating 2 BigInteger objects BigInteger b1, b2; b1 = new BigInteger("32145"); b2 = new BigInteger("7613721"); // apply floatValue() method float floatValueOfb1 = b1.floatValue(); float floatValueOfb2 = b2.floatValue(); // print floatValue System.out.println("floatValue of " + b1 + " : " + floatValueOfb1); System.out.println("floatValue of " + b2 + " : " + floatValueOfb2); } } Output: floatValue of 32145 : 32145.0 floatValue of 7613721 : 7613721.0 Example 2: When return float is too big for a magnitude to represent as a float. Java // Java program to demonstrate floatValue() method of BigInteger import java.math.BigInteger; public class GFG { public static void main(String[] args) { // Creating 2 BigInteger objects BigInteger b1, b2; b1 = new BigInteger("32145535361361525377"); b2 = new BigInteger("7613721535372632367351"); // apply floatValue() method float floatValueOfb1 = b1.floatValue(); float floatValueOfb2 = b2.floatValue(); // print floatValue System.out.println("floatValue of " + b1 + " : " + floatValueOfb1); System.out.println("floatValue of " + b2 + " : " + floatValueOfb2); } } Output: floatValue of 32145535361361525377 : 3.2145535E19 floatValue of 7613721535372632367351 : 7.6137214E21 Reference: https://docs.oracle.com/javase/7/docs/api/java/math/BigInteger.html#floatValue() Comment More infoAdvertise with us Next Article BigInteger floatValue() Method in Java A AmanSingh2210 Follow Improve Article Tags : Java java-basics Java-Functions java-math Java-BigInteger Java-math-package +2 More Practice Tags : JavaJava-BigInteger Similar Reads Java Tutorial Java is a high-level, object-oriented programming language used to build web apps, mobile applications, and enterprise software systems.
