Function: Fak
Calculates the factorial of a number.
ReturnValue = Fak(Value)
Input Parameters
| Specifies an integer value, a variable, or a data channel that contains integer values. |
Return Parameters
| ReturnValue | Returns integer values. |
Examples
The following example calculates the factorial of the number 6.
| VBScript | Python |
Dim intMyResult intMyResult = Fak(6) 'intMyResult = 720
The following example calculates the factorial of the values in the Group1/Input data channel and saves the result in the Group2/Result data channel.
| VBScript | Python |
Call Calculate ("Ch(""Group2/Result"")= Fak (Ch(""Group1/Input""))")
 | Note You must use the Calculate command in scripts to calculate data channels with formulas. Compute the data channels according to the syntax in the Calculator. Refer to the procedures Executing Channel Calculations in the Calculator and Assigning a Value to a Variable in the Calculator for more information about the Calculator. |
 | The input quantity must be dimensionless. The physical result quantity is also dimensionless. The Input and Result Quantities for Quantity-Based Calculations page contains an overview of the input quantities and result quantities of all functions. Refer to the Help page Calculating Quantity-Based and Non-Quantity-Based in DIAdem for the conditions and rules for quantity-based calculations. |
