Factorial online

The **online factorial calculator** has the **factorial** function
which allows to **calculate online factorial** of an integer.

The exclamation point is generally used as a notation of the factorial, the calculator allows to use this notation.

For example, for **calculating the factorial of 5** , use the following syntax
factorial(5),
after calculation , the result 120 is returned.
The following syntax can also be used to calculate the factorial 5!

For small numbers, the calculator is able to give the details of the calculations of factorial.
