Example usage I've seen: $x^2 / (y // z)$

Context: I recently started learning some fundamental electrical engineering, where I saw

I calculated the power doing $vs² / (r1 + ron + ron // ron+r2)$

Where did you see it? Can you give more context? e.g. if you found this in a python program, the // operator would mean to divide then round down to the nearest integer. e.g. 3//2 == 1. –  Hurkyl Mar 31 '12 at 9:05
    
It's electrical engineering related, not programming. I've updated my question. :) –  user50849 Mar 31 '12 at 9:16

In an electrical engineering context, I would guess that $a // b$ probably means the equivalent single resistance for 2 resistors in parallel of size $a$ and $b$, which is $\frac{ab}{a+b}$.

This is also backed up by @pedja's comment to the question. Thanks. –  user50849 Mar 31 '12 at 13:32
