Large numbers in Java

In fact, the Java language does not model all objects in real life.

For example: real numbers. Java does not fully represent real numbers in life.

Integer.max_value: 2147483647

integer.min_value:-2147483648

If you exceed a number that represents less than 2147483648 or greater than 2147483647, you need to consider long

Long.max_value: 9223372036854775807

Long.min_value: -9223372036854775808

If long does not meet the requirements, BigInteger is required.

On the question of the King's reward for chess inventors, the first squares put 1 grains of wheat, the second one put 2 grains, and so on. Each of the cells is doubled from the previous one. The integer and long are not implemented correctly. Only with BigInteger.
