Vague, indeed....as you would round differently depending
upon the data type of the numbers involved. You can add
intergerss, floats (and doubles) and packed decimal numbers
in assembler - to which does this question refer?

As the second half of the Q addresses packed decimal, I will
assume that part one does as well...

There are various ways to round data - truncation is one
valid way, another is to move to the closest "whole value"
in the least significant digit desired in the result, or you
can mov4e to the closest number towards +infinity, or to the
closest towards -infinity, or the closest towards 0, etc.,
So first off, you need a better definition of "round". What
I think this question was attempting to get at was to see it
you know about the SRP (shift-and-round-packed) instruction,
which allows you to apply a rounding factor and shift the
packed decimal result to the desired number of significant
digits.
