the "zero" is not necessary. Thus I should connect "i" directly to
multiply in place of the "zero". But why the need of the DBL between
the "i" and the multiply?
The type
conversion from int32 (blue wire) to DBL (orange wire) is in your
code only indicated by a (hardly visible) grey dot at the input of the
multiply terminal. The explicit use of the DBL conversion means
clearer code since it makes the type conversion obvious.
Another possible modification of the code is to use of physical units.
The multiply by 0.0254 could be replaced by a conversion of the wire to
inches and a display of the length in meters. If that kind of code is
more 'readable', however, depends on the readers familiarity with the
unit feature of Labview.
