FACT Function

Computes a factorial.

Category:

Mathematical

Syntax

FACT(n)

Required Argument

n

is a numeric constant, variable, or expression.

Details

The mathematical representation of the FACT function is given by the following equation:

\begin{matrix} F A C T (n) = n! \end{matrix}

with n ≥ 0.

If the expression cannot be computed, a missing value is returned. For moderately large values, it is sometimes not possible to compute the FACT function.

Example

The following SAS statement produces this result.
