Examples of java.math.BigInteger.longValue()

java.math.BigInteger.longValue()
sun.com/docs/books/jls/second_edition/html/conversions.doc.html#25363">narrowing primitive conversion from {@code long} to{@code int} as defined in the Java Language Specification: if this BigInteger is too big to fit in a {@code long}, only the low-order 64 bits are returned. Note that this conversion can lose information about the overall magnitude of the BigInteger value as well as return a result with the opposite sign. @return this BigInteger converted to a {@code long}.

    BigInteger x = BigInteger.valueOf(n);
    BigInteger y = x.multiply(x.add(BigInteger.ONE));
    y = y.multiply(x.shiftLeft(1).add(BigInteger.ONE));
    y = y.divide(SIX_BI);
    y = y.mod(MODULUS_BI);
    return y.longValue();
