This sounds reasonable.

But the result could also be converted to the format that is the "closest and suitable" from the input format.

I mean: the user forced a format that is not floating point number for a reason of his/her own;
When it is possible, we should respect this choice.

So if the input is in uint8, the result could be computed in floating point number
then converted to uint8 if possible, or uint# if it is too large, or even kept as floating point number when required.

Don't know how heavy this is on a big matrix (a user probably select uint# to spare memory).

My two cents

regards
