Description
*Version noticed: 8.3.0
While testing graph track operations I noticed that the "Sqrt" operation is not functioning properly.
Instead of taking the Square Root of the values it raises the values to a power of 2.
Also, it adds the words "Power - " to the beginning of the track title undergoing the operation (a clear sign that the Sqrt operation is off).
It seems that this "Sqrt" function has been implemented to "Square" the values rather than finding the "SquareRoot" as the abbreviation indicates.

Sqrt now calculating square root
If someone tries to take the Sqrt of a graph containing negative numbers then math says the sqrt should be "i" (an imaginary number). This, however, can't be drawn on a graph. What IGB currently does is draw to negative infinity. Instead, the sqrt of negative portions of graphs should just draw as zero. (It would be nice to have a way to show discontinuity of the graph, but this is not currently possible with IGB's current graph implementation.)
It seems that the graphs being drawn to negative infinity is no longer a reproducible behavior. Possibly, code refactoring may have corrected this. Since this operation is now functioning as expected the story will now be closed.
My testing verifies that the "Sqrt" operation is now functioning properly after changes to the code. Since this story is resolved it will now be closed.
