FACT(N)

FACT() calculates the factorial of a number $N$ as 1*2*.....* $N$ .

FACT(N)

e.g. FACT(3) displays 6 as a result.

The factorial of a number $N$ is the product of all positive integers, less than or equal to $N$ . It is calculated as -

$N!=NX(N-1)X(N-2)X.....1$

e.g. FACT(1..5) calculates factorial of numbers from 1 to 5 and displays result as 1 2 6 24 120.
