Missing apoc.math.tanh in AuraDB

Neo4j Graph Platform Aura & Cloud

I'm running a regular AuraDB instance, and for some reason it appears to be missing the tanh function.

When I run: RETURN apoc.math.tanh(1) I get:

Neo.ClientError.Statement.SyntaxError
Unknown function 'apoc.math.tanh' (line 1, column 8 (offset: 7))
"RETURN apoc.math.tanh(1)"

I appear to be on the latest version:

return apoc.version()
"2025.01.0"

It certainly looks like it should be there; it's in the regular Apoc docs:

call apoc.help("tanh") comes back with no records.

What's going wrong here?

@neo4j6

APOC support - Neo4j Aura describes the APOC procedures available on AuraDB of which apoc.math.tanh is not listed

However can you use something as described at Mathematical functions - trigonometric - Cypher Manual so as to get the equivalent of tanh.

Ahh, good to know, thanks. Out of curiosity, why does AuraDB support only a subset of functions?
