Java BigInteger class has the following built-in methods.
| Method |
Description |
| abs() |
It is used to get the absolute value of this BigInteger. |
| add() |
It is used to add the given BigInteger (val) to this BigInteger [i.e. (this BigInteger) + (BigInteger val)]. |
| and() |
It is used to perform and operation between this BigInteger and the given BigInteger (val) [i.e. (this BigInteger) & (BigInteger val)]. |
| andNot() |
It is used to perform andNot operation between this BigInteger and the given BigInteger (val) [i.e. (this BigInteger) & (~BigInteger val)]. |
| bitCount() |
It is used to count the number of bits in 2's complement denotation of this BigInteger. |
| bitLength() |
It is used to return the number of bits in minimum 2's complement denotation of this BigInteger without including a sign bit. |
| clearBit() |
It is used to clear the set bit at the given indices from this BigInteger if exists. |
| compareTo() |
It is used to compare to this BigInteger object with the given object or in other words we can say this method it compares two objects of "BigInteger" type. |
| divide() |
It is used to divide this BigInteger by the given BigInteger (divsr) (i.e. this BigInteger / BigInteger ). |
| divideAndRemainder() |
Returns BigInteger array of 2 elements that contain quotient that is calculated by using (this BigInteger)/(BigInteger val) followed by the remainder that is calculated by using (this BigInteger) % (BigInteger val). |
| doubleValue() |
It is used to convert this BigInteger into a double and when this BigInteger value is large enough to fit in a long so it will be converted to either Double.POSITIVE_INFINITY or NEGATIVE_INFINITY. |
| equals() |
It is used to check whether this BigInteger and the given object are equal or not. |
| flipBit() |
It is used to flip the bit indexed at the given position in this BigInteger. |
| floatValue() |
It is used to convert this BigInteger into a float. |
| gcd() |
It is used to return the greatest common divisor of the absolute of this BigInteger and the given parameter (val). |
| getLowestSetBit() |
It is used to returns the index of 1's bit from the rightmost side in this BigInteger. |
| hashCode() |
It is used to return the hash code value of this BigInteger. |
| intValue() |
It is used to convert this BigInteger into an integer. |
| isProbablePrime() |
It is used to check whether this BigInteger is probable prime or not. |
| longValue() |
It is used to convert this BigInteger into a long. |
| max() |
It is used to get the highest value from both of the compared object (this BigInteger and BigInteger val). |
| min() |
It is used to get the least value from both the compared object (this BigInteger and BigInteger val). |
| mod() |
It is used to calculate the mod by using (this BigInteger % BigInteger val). |
| modInverse() |
It is used to calculate the mod inverse by using the inverse of (this BigInteger) mod the given BigInteger (val). |
| modPow() |
It is used to calculate the mod pow by using the (this BigInteger) raised to the power of the first given argument (exp) mod the second given parameter [i.e. (this BigInteger) pow (exp) mod (BigDecimal val) ]. |
| multiply() |
It is used to represent the value of this BigInteger multiplied by the given argument. |
| negate() |
It is used to negate the value of this BigInteger. |
| nextProbablePrime() |
It is used to get the next probable prime number that should be higher than this BigInteger and there is a limit of composite number that should not be exceed 2 pow(-100). |
| not() |
It is used to perform not operation on the value of this BigInteger. |
| or() |
It is used to perform OR operation between the value of this BigInteger and the value of the given BigInteger. |
| pow() |
It is used to calculate the pow by using the value of (this BigInteger) is raised to the power of the value of the given parameter (val) [i.e. (this BigInteger) pow (val) ]. |
| probablePrime() |
It is used to get the BigInteger that holds the positive probable prime value with the given length. |
| remainder() |
It is used to calculate the remainder by using this BigInteger value is to be divided by the given BigInteger value. |
| setBit() |
It is used to set the bit value "1" at the given position in this BigInteger. |
| shiftLeft() |
It is used to shift the given number of bits towards left side in this BigInteger. |
| shiftRight() |
It is used to shift the given number of bits to the right in this BigInteger. |
| signum() |
It is used to perform signum (sign number) function on this BigInteger. |
| subtract() |
It is used to subtract the given value from the value of this BigInteger. |
| testBit() |
It is used to check whether the testing bit indexed at the given position is set or not in this BigInteger. |
| toByteArray() |
It is used to convert this BigInteger to a byte [] that holds 2's complement denotation of this BigInteger and the array capacity is enough to represent this BigInteger with one extra bit for sign. |
| toString() |
It is used to represent decimal string of this BigInteger. |
| valueOf() |
It is used to represent the given long value into a BigInteger. |
| xor() |
It is used to perform xor operation between this BigInteger. |
