With the latest MSVC update the build breaks on Windows with this error:
`error: calling a __host__ function("__floorf") from a __global__ function(...) is not allowed`
This happens due to the use of `floor` reverting to a host function for float arguments, whereas the correct usage of `floorf` is calling a device function.
