Example below demonstrates working of bigdecimal class toBigInteger method. Method default return type is a biginteger class object value.
Java bigdecimal toBigInteger example
Example below demonstrates working of bigdecimal
class toBigInteger method. Method default
return type is a biginteger class object
value. If the bigdecimal object value is 201.0, method will return 201 as
biginteger objects cannot hold double type values.
Method generates NumberFormatException, if it finds
the bigdecimal value other than integers and double
types values.
Syntax for using the method: public
BigInteger toBigInteger()
BigDecimal obj = new BigDecimal(integer);
BigInteger bigInt = new BigDecimal("String");
bigInt = obj.toBigInteger();
System.out.println(bigInt);

import java.math.BigDecimal;
import java.math.BigInteger;
import java.math.MathContext;
public class Java_bigdecimal_toBigInteger {
public static void main(String args[]) {
BigInteger bigInt = new BigInteger("0");
BigDecimal big_0 = new BigDecimal(Math.PI);
bigInt = big_0.toBigInteger();
System.out.println(" BigDecimal value :" + big_0
+ "\nmethod generating BigInteger value" +
" :" + bigInt);
big_0 = new BigDecimal(Math.E);
bigInt = big_0.toBigInteger();
System.out.println("\n BigDecimal value :" + big_0
+ "\nmethod generating BigInteger value" +
" :" + bigInt);
big_0 = new BigDecimal(20.2);
bigInt = big_0.toBigInteger();
System.out.println("\n BigDecimal value :" + big_0
+ "\nmethod generating BigInteger value" +
" :" + bigInt);
big_0 = new BigDecimal(325.02535);
bigInt = big_0.toBigInteger();
System.out.println("\n BigDecimal value :" + big_0
+ "\nmethod generating BigInteger value" +
" :" + bigInt);
}
