Untested and Unbenched CUDA Features

**Describe the bug**
Currently, the CUDA ops for datatypes other than F32 remain untested, and casting will be unclear. Especially for floating-only operations like sin and cos.

**To Reproduce**
Not Applicable

**Expected behavior**
Ideally, there should be an assertive test for every datatype with correct casting and rounding to ensure stable operation. Also, for downcasting, there should be warnings.
