In other words, there is official support for the given range of numbers in BigIntegers, however, you can unofficially use it for even larger numbers if you have enough computing resources for it. BigDecimal and BigInteger in Java | Baeldung Guide to Java BigInteger | Baeldung abs () It returns a BigInteger whose value is the absolute value of this BigInteger. The BigInteger class is immutable, hence you can't change its state. Finally, we discussed the limitations of BigIntegers in regards to their immutability and the maximum size of the numbers they can store.
