Expressions with double "==" call out or Double "||". Whats the meaning?

[3dr]

Example "==":
if(DIR==L_R)(9*PITCH_ALL)else if(STATION==6)(PITCH_ALL)else((STATION-4)*PITCH_ALL)

Example "||": (OR)
if(SLUG_TYPE==FILLET||SLUG_TYPE==RECTANGLE||SLUG_TYPE==MICKEY)(1)else(0)

I thought I'd seen it all when it comes to these symbols.
I'm in some wizard files and seeing this. Not sure these would be formatted like this.

The double equal sign, "==", is a test for equality (if a == b then...). The double pipe, "||", is the logical OR operator. The full list can be found in the docs; search for "expression syntax operators" or have a look here:

I am still not sure why the documentation states
"| or ||" means Logical OR.

I have used both variants and both seem to do the same job.
But, is there a difference between "=" and "==" ?
My tests say they do the same or are "==" MUST be equal and "=" SHOULD be equal ? ;-)

I Think the developer had in mind the possibility to use != (Not Equal) Keep it two characters for the condition...

NX treats a single or double the same way.
A quick google shows that Java uses "==" & "||"

Could be that they guys making these seed files are just writing in the format they're more familiar with.
Just doesn't matter.

Normally a double equal (==) is used for a comparison check as stated above. If a == b then …
A single equal (=) is used to set a variable to a value. C = 4.5.
Combined, you can write: If A == B then C = 4.5

Earlier version of NX required "==" and "||" ... newer versions allow "=" and "|"
