====== Empty() ======
Category:  Special function

\\ 
=====Description=====
This function creates an [[syntax:types#empty_values|empty value]].

\\ 
=====Use cases=====
Use //empty()// to insert empty values into cells, or within other functions.

\\ 
=====Arguments=====
This function does not require arguments.

**Return value type:** Empty value

\\ 
=====Remarks=====
While a value can be tested for an empty value using a "value = empty()" expression, the [[syntax:functions:isempty|IsEmpty]] function can also be used.  The two approaches are equivalent.

\\ 
=====Examples=====

  [Content] = empty()  //Returns TRUE if [Content] contains an empty value, otherwise, FALSE.

  coalesce(empty(), 'ABC', '')  //Using empty() as an argument within a function.

  if( [Value] = 10, 'Ten', empty() )  //Using empty() to set a return empty value in an If statement.
