Zitat von complex.numbers

If z is an lvalue expression of type cv complex<T> then:

• the expression reinterpret_­cast<cv T(&)[2]>(z) shall be well-formed,
• reinterpret_­cast<cv T(&)[2]>(z)[0] shall designate the real part of z, and
• reinterpret_­cast<cv T(&)[2]>(z)[1] shall designate the imaginary part of z.

Moreover, if a is an expression of type cv complex<T>* and the expression a is well-defined for an integer expression i, then:

• reinterpret_­cast<[i]cv T*>(a)[2*i] shall designate the real part of a, and
  
• reinterpret_­cast<[i]cv T*>(a)[2*i + 1] shall designate the imaginary part of a[i].
