To answer this question, we need to understand the properties and limitations of the FACTORIAL function when using ARITH (COMPAT).
The FACTORIAL function calculates the factorial of a given integer. The factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example, 5! = 5 × 4 × 3 × 2 × 1 = 120.
When using ARITH (COMPAT), the maximum value of the integer argument to the FACTORIAL function is limited by the size of the data type used to store the result. In this case, we can assume that the data type used can store values up to its maximum value.
From the given options, we need to determine the maximum value that the FACTORIAL function can handle.
Option A) 20 - This option suggests that the maximum value is 20.
Option B) 29 - This option suggests that the maximum value is 29.
Option C) 28 - This option suggests that the maximum value is 28.
Option D) 18 - This option suggests that the maximum value is 18.
The correct answer is option C) 28. This option is correct because the maximum value of the integer argument to the FACTORIAL function when using ARITH (COMPAT) is 28.
