BigInteger doubleValue() in Java

doubleValue(): This method is available in java.math.BigInteger class of Java.

Syntax:

double java.math.BigInteger.doubleValue()

This method converts this BigInteger to a double. This conversion is similar to the narrowing primitive conversion from double to float as defined in The Java Language Specification: if this BigInteger has too great a magnitude to represent as a double, it will be converted to Double.NEGATIVE_INFINITY or Double.POSITIVE_INFINITY as appropriate.

Returns: this BigInteger converted to a double.

For Example:

BigInteger bigInteger = new BigInteger("12354")

bigInteger.doubleValue()  = > It returns 12354.0

Approach

Java

import java.math.BigInteger;

public class BigIntegerdoubleValue {
    public static void main(String[] args) {

        BigInteger bigInteger = new BigInteger("12354");
        System.out.println(bigInteger.doubleValue());
    }
}

Output:

12354.0
