I mean if it has a reason I don't know what it is. Also if it has no reason there is a really good vector struct:

template<typename T>
struct vector2 {
   T r, i;// r: Real, i: Imaginary
   template<typename T0> vector2(const vector2<T0>& R) : r(R.r), i(R.i) {} vector2() : r(0.f), i(0.f) {}
   template<typename T1, typename T2> vector2(const T1& i1, const T2& i2) : r(i1), i(i2) {}
   template<typename T0> vector2(const T0 R[2]) : r(R[0]), i(R[1]) {}

   template<typename T0> const vector2<T>& operator =(const vector2<T0>& R) { r = R.r; i = R.i; return this; }
   template<typename T0> const vector2<T>& operator%=(const vector2<T0>& R) { r %= R.r; i %= R.i; return this; }
   template<typename T0> const vector2<T>& operator+=(const vector2<T0>& R) { r += R.r; i += R.i; return this; }
   template<typename T0> const vector2<T>& operator-=(const vector2<T0>& R) { r -= R.r; i -= R.i; return this; }
   template<typename T0> const vector2<T>& operator*=(const vector2<T0>& R) { r *= R.r; i *= R.i; return this; }
   template<typename T0> const vector2<T>& operator/=(const vector2<T0>& R) { r /= R.r; i /= R.i; return this; }
   template<typename T0> const vector2<T>& operator&=(const vector2<T0>& R) { r &= R.r; i &= R.i; return this; }
   template<typename T0> const vector2<T>& operator|=(const vector2<T0>& R) { r |= R.r; i |= R.i; return this; }
   template<typename T0> const vector2<T>& operator^=(const vector2<T0>& R) { r ^= R.r; i ^= R.i; return this; }
