For my numerical analysis class, we use a certain symbol to represent the floating point square root operation (similar to using
\ominus for floating point subtraction,
\oplus for floating point addition, etc.). In order to render this in a LaTeX document, I'd need to somehow draw a similarly-sized circle over the "v" part of the square root symbol, but I'm not too familiar with tikz and don't really know how to start working on this.
The most important aspect is making sure the circle has the same size as the one for the
\oxxxx symbols. How would I go about making this? (And potentially, is there a better, more standard way to denote this operation?)
Added a picture to make what I'm asking for a tiny bit clearer.
