Cos(90) returning a value very close to 0, but I need 0?

Question

The values for temp_x_btm_left = 0 & temp_y_btm_left=1;

angle = 90;

//Moving the bottom left coordinates
_btm_left.real() = (temp_x_btm_left * cos(angle         


        

Answer 1

As long as |v1-v2| < predefinedDelta, simply consider v1 == v2.
