Source (N7:3) to the Destination (F8:12), converting from one
data type to another This overwrites the original value in
the Destination.

When the input conditions are true, the controller passes the
value in the Source (D9:3) through the Mask (D9:5) and stores
t
result in the Destination (D9:12). This overwrites the original
value in the Destination.
