Store a number that is longer than type long in Java [duplicate]
How can I store a number that is longer than the long type (MAX: 9223372036854775807) in Java?
For example the number 9223372036854775820.
Thanks in advance.
BigInteger if you work with a long and use
BigDecimal if you work with floatingpoint numbers. The
BigInteger can as big as you want, till there is not enough RAM.
BigInteger bd = new BigInteger("922337203685477582012312321"); System.out.println(bd.multiply(new BigInteger("15"))); System.out.println(bd);
But have to use the
BigInteger methods to do calculations and in the example you see that
BigInteger is immutable.
