FACTUNTIL (Number,NumberTill)

This function shows the factorial value up to the mentioned value.
In $FACTUNTIL(Number,NumberTill)$ , $Number$ is the value to start and $NumberTill$ is the maximum limit value.
Factorial means the result of multiplying a sequence of descending natural numbers down to 1.
So the factorial $n!$ is defined for a positive integer n as:

$n!=n*(n-1)*...2*1$ .
