Rotation over 360 degrees

Hello all,

I am trying to rotate an object beyond 360⁰. For example I want to rotate it to 450⁰, which equals to 90⁰, but instead of rotating only from 0⁰ to 90⁰, I want to have one full rotation (0⁰ to 360⁰) and then another 90⁰, I need that for better animation. For now I have no idea how to make that, I hope that I can find some help here, thank you.

DO NOT ever read from .eulerAngles.

Notes on clamping camera rotation and NOT using .eulerAngles because of gimbal lock:
