BugFix: Unable to cast floating point to enum.

[Robadob]

Addresses the below issue, actual reproduction unclear (builds with vs2019 and vs2022 for me).

Can confirm that the bug occurs on my laptop CUDA 11.7, VS2019 platform toolset v142 (reported in project properties although this appears as v160 in logs???), cmake 3.23.

PR fixes the build issue so happy to merge.
