There's:
It's used to calculate the distance between the end of 1 element
in a tuple and the start of the next element so that that next
element will have the proper alignment. IOW, if:
aligned_offset<Offset,Alignment>::remainder != 0
then there will be padding in the amount:
value-Offset
That is, IIRC.
HTH.
