Not sure where to put this question. But if anyone knows the answer awesome,

So I know how to find 10's complement of a whole number but does anything change if say I have a number with fractional portion?

ex.

9 9 9 10

6 4 5 2

answer: 3548

ex.

9 9 9 10

6 5 4. 3 0

=345.70

OR IS IT.....

9 9 10 9 10

6 5 4. 3 2 0

= 346.680
