Review comment:
The variety of generator dispatchers available in the compute kernel are
not consistent with their names. At some point we should rename them
consistently, but that is out-of-scope for this PR. Nevertheless, I suggest to
change the name of this generator dispatcher to
`GenerateUnaryArithmeticFloatOutType`. This is simply a suggestion, we can
rename later.
