Calling Sequence

type(expr, `!`)

Parameters

expr

any expression

Description

• 

This function will return true if expr is a factorial, and false otherwise.  For more information about factorials, see factorial.

• 

An expression of the type n!, where n is an integer, is not of type `!`, since its value is calculated before the call to the type function is executed.

• 

Note that the factorial function is both of type function and type `!`. In the function call, it is important that the exclamation mark, !, be enclosed in quotes.  Missing quotes will cause a syntax error.
