neo4j cypher toInt function

Question

In the neo4j Cypher refcard (http://docs.neo4j.org/refcard/2.0/) under Functions sections there is this definition:

toInt({expr})

Converts the given input in an integer if possible; otherwise it returns NULL.

If I try it in Cypher console I get this:

neo4j-sh (?)$ match (n:Document) return toInt(n.date);
==> SyntaxException: Unknown function 'toInt' (line 1, column 27)
==> "match (n:Document) return toInt(n.date)"
==>                            ^
neo4j-sh (?)$ 

(In my case n.date is a string representation of that date.)

Also in the neo4j documentation there is not mention of this function: http://docs.neo4j.org/chunked/stable/query-function.html.

Can anyone solve this puzzle?
