We can convert the BigInteger value to the long data type and also can covert the long value to the BigInteger with the use of java.math.BigInteger class and its methods.
Java BigInteger long
java example program to convert the BigInteger value to long
We can convert the BigInteger value to the long data type and also can covert the long value to the BigInteger with the use of java.math.BigInteger class and its methods.
BigInteger bi = BigInteger.valueOf(123L);
Above lines of code creates a BigInteger object with the long value "123L" and to convert the BigInteger value to the long type we can use the method longValue() of the BigInteger class.
Long result = (bigInteger1.multiply(bigInteger2)).longValue();
Above lines of code converts the bigInteger1.multiply(bigInteger2), a BigInteger value to the long. In our java example we have converted a result of two BigInteger variables value to a long variable result. Here is the full example source code of BigIntegerLong as follows:
import java.math.BigInteger;
|
Output of the example is as follows:
C:\biginteger>javac BigIntegerLong.java C:\biginteger>java BigIntegerLong Result(in Long) is ==> 13868394935526 |
