FACT function

PRO BASIC

The FACT function in Jspreadsheet Formulas Pro is a mathematical function that calculates the factorial of a number. Essentially, it multiplies the given number by every integer less than it down to 1. For example, the factorial of 5 (expressed as 5!) would be 54321, which equals 120. This function is used when you want to perform such calculations within your Jspreadsheet.

Documentation

Returns the factorial of a number.

Syntax

FACT(x)

Parameter	Description
`x`	The non-negative integer for which to calculate the factorial.

Behavior

The FACT function calculates the factorial of a given number. A factorial of a number is the product of all positive integers less than or equal to that number. Here's how the FACT function handles different inputs:

Numbers: The function computes the factorial of the given number. For example, FACT(5) returns 120 because 5*4*3*2*1 equals 120.
Empty cells: If the FACT function is applied to an empty cell, it treats the cell as 0 and returns 1 because the factorial of 0 is 1.
Text: If the function is applied to a cell that contains text, it returns a #VALUE! error because the function requires a numerical argument.
Booleans: If the function is applied to a cell that contains a boolean value (TRUE or FALSE), it treats TRUE as 1 and FALSE as 0 and calculates the factorial accordingly.
Errors: If the function is applied to a cell that contains an error, it returns the same error.

Common Errors

Error	Description
`#VALUE!`	This error is returned when the function is applied to a cell that contains non-numeric data.
`#NUM!`	This error is returned when the function is applied to a negative number or a number larger than `170` because the factorial function is only defined for non-negative integers and the result of factorial calculations for numbers larger than `170` exceeds the maximum limit for numbers in Jspreadsheet.

Best practices

Always ensure that the argument to the FACT function is a non-negative integer. The function returns an error for negative numbers and non-integer values.

Be cautious when using the FACT function with large numbers. Factorial calculations grow rapidly and can exceed the maximum limit for numbers in spreadsheets for numbers larger than 170.

Avoid using the FACT function on cells that may contain non-numeric data to prevent #VALUE! errors.

Use error handling functions like ISNUMBER or IFERROR to handle potential errors when using the FACT function in complex formulas.

Usage

A few examples using the FACT function.

FACT(5)    // Returns 120 - factorial of 5  
FACT(0)    // Returns 1 - factorial of 0 is defined as 1  
FACT(1)    // Returns 1 - factorial of 1 is 1  
FACT(170)  // Returns the largest factorial value supported by Jspreadsheet  
FACT(-3)   // Returns #NUM! - factorial not defined for negative numbers
