The java.math.BigInteger.bitLength() method returns the number of bits in the minimal two’s-complement representation of this BigInteger, excluding a sign bit. For positive BigIntegers, this is… Read More
The java.math.BigInteger.setbit(index) method returns a Big-integer whose value is equivalent to this Big-integer with the designated bit set. The method computes (this | (1<<n)). The… Read More
The java.math.BigInteger.shiftLeft(int n) method returns a BigInteger whose value is (this << n). The shift distance, n, may be negative, in which case this method… Read More
Prerequisite: BigInteger Basics The java.math.BigInteger.negate() method returns a BigInteger whose value is (- this). negate() method will change the singned bit of BigInteger. Syntax: public… Read More
The java.math.BigInteger.and(BigInteger val) method returns a BigInteger whose value is bitwise-AND of two BigIntegers. This method returns a negative number if both of the BigIntegers… Read More
The java.math.BigInteger.andNot(BigInteger val) method returns a BigInteger whose value is (this & ~val) where this to the current BigInteger with which the function is being… Read More
The java.math.BigInteger.not() method is used to find the bitwise-NOT of a BigInteger. This method returns a negative value if and only if this BigInteger is… Read More
Prerequisite: BigInteger Basics The java.math.BigInteger.bitCount() method returns number of bits in the two’s complement representation of this BigInteger that differ from its sign bit. This method… Read More
Prerequisite: BigInteger Basics The java.math.BigInteger.flipBit(index) method returns a BigInteger which is used to flip a particular bit position in a BigInteger. This method Computes (bigInteger ^… Read More
Prerequisite: BigInteger BasicsThe clearBit() method returns a BigInteger which is used to clear a particular bit position in a BigInteger. The bit at index n… Read More
Prerequisite: BigInteger Basics The xor(BigInteger val) method returns bitwise-XOR of two bigIntegers. This method returns a negative BigInteger if and only if exactly one of… Read More
Prerequisite: BigInteger Basics The java.math.BigInteger.or(BigInteger val) method is used to perform bitwise OR of two BigIntegers. One of the BigInteger is passed in parameter and… Read More
Prerequisite: BigInteger Basics BigInteger max() method: The max() method of the BigInteger returns the BigInteger whose value is the greater between current BigInteger and BigInteger… Read More
Prerequisite : BigInteger Basics The probablePrime() method will return a Biginteger of bitLength bits which is prime. bitLength is provided as parameter to method probablePrime()… Read More
Prerequisite : BigInteger Basics The modPow() method returns modular multiplicative inverse of this, mod m. This method throws an ArithmeticException if m <= 0 or… Read More
