Compilation failure with real()/imag() on complex64

### 🐛 Describe the bug

When given `complex64` input, the `real()` and `imag()` ops try to call `std::realf()` and `std::imagf()` which do not exist, leading to a compile error. The fix is to add these ops to the `needFloatSuffix` switch statement.
