flip function
| Input type | Output type |
| complex | complex |
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.
