BigInteger intValue() Method in Java Last Updated : 07 Oct, 2022 Comments Improve Suggest changes Like Article Like Report The java.math.BigInteger.intValue() converts this BigInteger to an integer value. If the value returned by this function is too big to fit into integer value, then it will return only the low-order 32 bits. Further there is chance that this conversion can lose information about the overall magnitude of the BigInteger value. This method can also return the result with opposite sign. Syntax: public int intValue() Returns: The method returns an int value which represents integer value for this BigInteger. Examples: Input: BigInteger1=32145 Output: 32145 Explanation: BigInteger1.intValue()=32145. Input: BigInteger1=4326516236135 Output: 1484169063 Explanation: BigInteger1.intValue()=1484169063. This BigInteger is too big for intValue so it is returning lower 32 bit. Example 1:Below programs illustrate intValue() method of BigInteger class Java // Java program to demonstrate // intValue() 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 intValue() method int intValueOfb1 = b1.intValue(); int intValueOfb2 = b2.intValue(); // print intValue System.out.println("intValue of " + b1 + " : " + intValueOfb1); System.out.println("intValue of " + b2 + " : " + intValueOfb2); } } Output:intValue of 32145 : 32145 intValue of 7613721 : 7613721 Example 2: when return integer is too big for int value. Java // Java program to demonstrate // intValue() 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("4326516236135"); b2 = new BigInteger("251362466336"); // apply intValue() method int intValueOfb1 = b1.intValue(); int intValueOfb2 = b2.intValue(); // print intValue System.out.println("intValue of " + b1 + " : " + intValueOfb1); System.out.println("intValue of " + b2 + " : " + intValueOfb2); } } Output:intValue of 4326516236135 : 1484169063 intValue of 251362466336 : -2040604128 Reference: BigInteger intValue() Docs Comment More infoAdvertise with us Next Article BigInteger intValue() 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.
