You can use the BigInteger class for integers and BigDecimal for numbers with decimal digits. Both classes are defined in java.math package. Example: BigInteger reallyBig = new BigInteger("1234567890123456890"); BigInteger notSoBig = new BigInteger("2743561234"); reallyBig = reallyBig.add(notSoBig);

8 mar 2024 · It can handle very large and very small floating point numbers with great precision but compensating with the time complexity a bit. A BigDecimal consists of a random precision integer unscaled value and a 32-bit integer scale. If greater than or equal to zero, the scale is the number of digits to the right of the decimal point.
