convert ingest processor does not convert float to integer #128160

OS Version

Problem Description
The convert ingest processor does not successfully convert from float to integer types and this absence of capacity is not excluded by the documentation. Either it should be documented that convert is not a general purpose conversion processor or the capacity should be added (preferably the latter).
Steps to Reproduce
