FACTUNTIL (Number,NumberTill)
- is the minimum number.
- is the maximum number.
is the minimum number.
is the maximum number.Description
- This function shows the factorial value up to the mentioned value.
- In , is the value to start and is the maximum limit value.
- Factorial means the result of multiplying a sequence of descending natural numbers down to 1.
- So the factorial is defined for a positive integer n as:
, 
is defined for a positive integer n as:.
.
- For example FACTUNTIL(9,4) calculates the value of 9*8*7*6*5.
Examples
- FACTUNTIL(10,7) = 720
- FACTUNTIL(54,45) = 1929772710028800
- FACTUNTIL(9,6.2) = 504
