How to plot 1/x^x in Blender using Z function surface

Question

I am looking to plot math functions in Blender using the Z function surface Add-On.

It works great for functions such as:

1/x**2

But fails for functions like:

1/x**X

which gives error:

Error evaluating expression: 1/( x**x ) (Check the console for more info)

The console shows:

TypeError: can't convert complex to float

...despite Google and Wolfram Alpha being able to plot these easily:

You can wrap your expression in parens add a .real or .imag to get the real or imaginary part, e.g. (1/(x**x)).real.
