Material graph power node doesn't allow negative base?

[ClockworkOcean]

It’s to do with the fact that shaders can’t show you negative values:

[bug] power don't work with negative values in Decals

But power doesn’t work like that - so it is a bug. If you want to add such node which works like that then add another one - don’t mess with basic math please. I fount this only in one place right now - obvious to fix, but it can cause a lot more bugs, and why? this change is totally illogical and counter-intuitive.
