Floating point types (float,doubleandlong double) cannot precisely represent some numbers because they have finite precision and represent the values in a binary format. Just like we have repeating decimals in
The memory address "0" has a special significance; it signals that the pointer is not intended to point to an accessible memory location. But by convention, if a pointer contains the null (zero) value, it is assumed to point to nothing....
