What function the Solidworks parallel constraint symbol mean in MathCAD?

[astevenson-2]

In investigating an unrelated problem, I found a very useful xmcd file on this discussion board. But there is a symbol I don't recognize. Can someone tell me what the circled operators in the image below do?

Also a nice feature would be to hover over an operator and for a popup to appear saying what the operator is and link to the help file for that operator.

Is it defined in the worksheet?  Can you post a link to the worksheet, please?

Sorry for my atrocious English in the original post. I'm from Texas; what do you expect. Regardless, the file with the mystery parallel symbol was retrieved from this thread:

Well, you can find this symbol in the "Custom Characters" toolbar (in main menu select "View" --> "Toolbars" --> "Custom Characters"):

Thanks Vladimir. I found the help file using Custom Characters help file and see what the parallel symbol accomplishes. Interesting there are no hits from help when searching for "parallel". Pretty esoteric.

Not esoteric at all. Its just a custom character, a symbol, not a predefined function. On its own it accomplishes nothing at all.

In the sheet you referenced there are a couple of closed regions. Right at the beginning if you open the first region you will find a function defined for the calculation of the parallel connection of resistors. This function was given the "name" // using that custom character.

Later in the sheet this very function is used using the infix notation
