Cleanup the use of Float primitive wrapper. As of Java 9, the VM can do a better job of handling the (#3890)

BradWalker · web-flow · commit 190ffcb94003 · 2022-04-03T07:54:51.000-06:00
coversion from a float primitive to a Float Object or vice versa. This is an extension of the work done in #2498. No tests have been touched as those expressly need to manage the conversion.
