I'm interested as to what value of C9 gives you that result? I would have
expected COS(C9) and SIN(C9) to have the same +ve value only for
C9=RADIANS(45) [and multiples of 2*PI() beyond that], and in that case the
values would be SQRT(2), not 0.564642473395035
But to answer your formatting question, perhaps
=COMPLEX(ROUND(COS(C9),2),ROUND(SIN(C9),2))
