' Iterative solution
Function iterativeFactorial(ByVal n As Long) As Long
Dim factorial As Long = 1
For i As Long = 1 To n
factorial *= i
Next
Return factorial

End Function
Factorial is a Mathematical Function.
Factorial returns the product of all numbers from 1 to itself
e.g. Factorial 5 = 5*4*3*2*1 = 120
It is expressed as n! = factorial of n
To implement it in Visual Basic, there are two methods-
Function factorial(ByVal n as Integer) as Integer
If n =< 1 Then factorial = 1:Exit Function
factorial = n * factorial(n-1)
End Function
Function factorial(ByVal n as Integer) as Integer
factorial = 1
Dim a as Integer
For a = 1 to n
factorial = factorial * a
Next 'a
End Function
dim num as integer, factorial as single
num=inputbox("enter a number")
factorial = 1
for x = 1 to num
factorial = factorial * x
next x
print"factorial is" ; factorial
or By Recursive Method
Private Function FindFactorial(number As Integer)
If number < 1 Then
FindFactorial = 1
Else
FindFactorial = number * FindFactorial(number - 1)
End If
End Function
' recursive is faster and simpler for finding factorial

Rounding in Visual Basic is the method of rounding an integer up, or flooring an integer, which is rounding down. To round up, you use the System.Math.Round function. To round down, or floor, you use the System.Math.Floor function.
Visual Basic Controls work on Visual Studio for Visual Basic and Applications that made by Visual Basic.
#!/usr/bin/perl print factorial($ARGV[11]); sub factorial { my($num) = @_; if($num == 1) { return 1; # stop at 1, factorial doesn't multiply times zero } else { return $num * factorial($num - 1); # call factorial function recursively } }
Visual Basic was started in 1991.
A function is essentially a subroutine that is ment to be used by other subroutines.
