Enum-Variable with float

Is there a way to declare an enum-variable carrying float-variables? This site says the variables are constant integers by default: JavaScript Enum.

So my question is: Can I make something like this?

enum axesvar {x, y, z};
axesvar.x = 10.3;
axesvar.y = 5.1;
axesvar.z = 5.2;

The variables of course shall not become constants.

Even though the command struct exists in JavaScript, it doesn’t work with Unity-Javascript!

A possible workaround is here.

Therefore I dis-marked the other answer as correct.

Furthermore, the workaround doesn’t seem to be clean and is still causing me trouble. New threat is here: How to use struct-variables as return-values of functions
