---

When using the apoc.export.csv.graph with the parameter useType:true, then the FLOAT properties are not exported. When using useType:false (the default) the the FLOAT property exported as string.

Expected Behavior (Mandatory)

The property value should be exported and the header should contain "propname:float" for the property with type FLOAT

Actual Behavior (Mandatory)

The header contains "propname:int" and the value is empty string

How to Reproduce the Problem

CREATE (n:TestNode) SET n = {valFloat:toFloat(123), name:'NodeName'}; CALL apoc.graph.fromCypher("MATCH (n:TestNode) RETURN n", {}, 'TestNode.csv',{}) YIELD graph CALL apoc.export.csv.graph(graph, null, {stream:true,useTypes:true}) YIELD properties, rows, data return properties, rows, data;
