This function has been deprecated and will be removed in version 5.0. The functionality is replaced by the Neo4j functions toFloat(value) and the more permissive toFloatOrNull(value). The Neo4j functions do not have exactly the same behavior as the APOC ones - the following table is intended to assist migration by highlighting the differences:
