I Intuition for Euler's identity

[Prem1998]

I read an intuitive approach on this website. You should read it, it's worth it:
https://betterexplained.com/articles/intuitive-understanding-of-eulers-formula/

I read that an imaginary exponent continuously rotates us perpendicularly, therefore, a circle is traced and we end up on -1 after rotating through pi radians.
If that's true, then why doesn't e^-pi rotates us continuously through 180 degrees so that we end up on the negative axis? '-' has more rotating power than 'i',right?
And, if that's not true, then please share your intuition of the formula.

No. The real part of the exponent does no rotation at all. Suppose we separate the exponent x+iy, into its real part, x, and its imaginary part, iy. Then e^x+iy = e^xe^iy, where the factor e^x is the usual real exponential and e^iy is a pure rotation in the complex plane. e^x is just a pure multiplier with no rotation of the vector e^iy in the complex plane. So e^-π does no rotation at all.
