get euler rotation from horizontal and vertical axis values

Hi, I am trying to rotate my character depending on the value coming from the joystick. is there a way without putting full blown trigonometry into my script to convert the horizontal and vertical axis values to a euler angle. so if Input.GetAxis("Horizontal") == 1 and Input.GetAxis("vertical") == 1 the euler angle would be 45. and if Input.GetAxis("Horizontal") == 1 and Input.GetAxis("vertical") == -1 the euler angle would be 135.

i only know how to do this with a ton of if else statements. im sure there is a better way, i just cant find the right function.
