Correct the "not" symbol by removing the invert dot in the icon

Status: New

Suggestion: Correct the symbol of the "not" primitive function by removing the invert dot on the input node in the icon.

 

currently: source: http://zone.ni.com/reference/en-XX/help/371361H-01/glang/not/

That means in exact words of the LabVIEW design the following: negate and negate; first negate due to the invert dot at the input, then negate again due to the "not" function.

 

suggestion: notfunct[1].gif That means negate (only once). See also http://en.wikipedia.org/wiki/Negation

 

IMHO, unless this is corrected, other ideas have no chance to be implemented consistently, such as: Negate input on boolean functions

 

Thank you for reading!

Liked the "¬" only. I think it should be corrected, even though I never had a problem with the current way.

With the proliferation of negation bullets in the Compound Arithmetic operator:

my brain is starting to read this:

as NOT NOT (i.e. nop).

I believe a refreshing of that icon is in order...

Looking at the comments on this idea, I ended up searching invert, negate, bubble, and circle (skipping anything that was already marked duplicate).  I figured I might as well link the related ideas.

A couple people (not in this idea) mentioned making inversion bubbles more visible:
