WebPython supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long and is separate from the int type, but the interpreter will automatically use whichever is more appropriate. In Python 3.0+, the int type has been dropped completely.. That's just an implementation detail, though — as long as you have … WebThe idea is just using more bits to store information. Let's say an "int" type has 64 bits. You can represent 64 digit binary numbers with it. By using more of it, you can represent bigger numbers. For example, 4 "int"s can represent 256 digit binary number. I …

Languages like Java, Python, Ruby etc. can handle big integers, but we need to write additional code in C/C++ to handle huge values. Description of program : The below program can calculate factorial of any number, i.e. factorial of numbers above 20 which is not feasible for an 64 bit computer.
