32-bit float

Im wondering what or if theres a difference in quality (meaning a deviation from bit-perfection) of having the same music as 32-bit float or 24-bit (int).

assuming a soundcard can record in 24-bit but still do processing with 32-bit float, could the recorded file processed in 32-bit float then have more quality than before? I guess not.

but what if then dithering down to 24-bit from 32-bit float? is there a real loss of quality? or are only zero-bytes being reduced?

it seems that after certain processes like resampling, at least some tools automatically convert the processed file to 32-bit float during that process (of course, resampling is already loss of quality, but I'd like to know just about the difference in bitdepth)
