An exception is thrown if this BigDecimal has a nonzero fractional part. Syntax: public BigInteger toBigIntegerExact() Parameters: The method does not take any parameters. Return value: This method returns the value of BigDecimal object converted to a BigInteger. Examples: Input: (BigDecimal) 1213 Output: (BigInteger) 1213 Input: (BigDecimal) 12785412 Output: (BigInteger) 12785412 Below programs illustrates the working of the above mentioned method: Program 1: Java // Program to demonstrate toBigIntegerExact() method of BigDecimal import java.math.*; public class gfg { public static void main(String[] args) { // Assigning BigDecimal b BigDecimal b = new BigDecimal("1213"); // Assigning the BigIntegerExact value of BigInteger b to BigInteger i BigInteger i = b.toBigIntegerExact(); // Printing i value System.out.println("BigInteger value of " + b + " is " + i); } } Output: BigInteger value of 1213 is 1213 Program 2: Java // Program to demonstrate toBigIntegerExact() method of BigDecimal import java.math.*; public class gfg { public static void main(String[] args) { // Assigning BigDecimal b BigDecimal b = new BigDecimal("12785412"); // Assigning the BigIntegerExact value of BigInteger b to BigInteger i BigInteger i = b.toBigIntegerExact(); // Printing i value System.out.println("BigInteger value of " + b + " is " + i); } } Output: BigInteger value of 12785412 is 12785412 Comment More infoAdvertise with us Next Article Introduction to Java T Twinkl Bajaj Follow Improve Article Tags : Misc Java Java-Functions java-math Java-BigDecimal Java-math-package +2 More Practice Tags : JavaMisc Similar Reads Java Tutorial Java is a high-level, object-oriented programming language used to build web apps, mobile applications, and enterprise software systems.
