What is the impact on performance when using float versus double in mathematical calculations in C++?
- float is faster
- double is faster
- No difference
- It depends on context
While "float" may use less memory, "double" provides higher precision. The performance impact depends on the architecture and context. Some architectures are optimized for double precision, making operations as fast, if not faster, than float operations.
