flip function

This function exchanges the real and the imaginary parts of the argument and returns the result. It is defined as follows:

flip(a + bi) = b + ai

Examples:

flip(2)        ; (0, 2)
flip(8.6)      ; (0, 8.6)
flip((3, 4))   ; (4, 3)
flip((-7, 4))  ; (4, -7)

Note: this function is often convenient for composing a complex number using two float expressions. For example, the expression real(z) + flip(imag(z)) is equal to z.
