|
| What's the difference between the two and are there circumstances where it would effect training? |

Double float is a higher precision, than a single float. But also potentially slower (only matters with large designs) and less tested (because rarely used).
Double float elements could be useful in some special situations, for example with very high precision ADC converters (more than 24 bits). But in most cases single float is perfectly enough.
I would stick with single float designs. And only use double float when really needed (they can be mixed). |

| Okay, and what about scalar and vector elements? |

| Those are unrelated. Scalar has one value. Vector has many. |
