What is the best casting method to use when casting int to uint32_t?

Should I use (uint32_t)num, or reinterpret_cast<uint32_t>(num), or static_cast<uint32_t>(num)? (Or something else)?

I know that there are many explanations out there regards the different casting types, but I want to ask specifically about primitive types.

What do you want to happen if `num` is negative? – NathanOliver Oct 23 '17 at 17:59
@NathanOliver - in my specific use case I can assume it won't be negative (means the result can be undefined) – ElyashivLavi Oct 23 '17 at 18:00
