This is a question Irrational people

Freddie Woo tells us "I'm having to drive 500 miles to pick up my son from the ex's house because she won't let him take the train in case he gets off at the wrong station. He's 19 years old and has A-Levels and everything." - Tell us about illogical and irrational people who get on your nerves.

it's both
it's imaginary because it has no real part, and irrational because it can't be written as fraction of two real numbers

I didn't know that numeric rationality had reality as a criterion.

rational numbers are a subset of real numbers, which in turn are a subset of complex numbers
the set of complex numbers comprises real numbers, imaginary numbers and numbers which consist of a real part plus an imaginary part

though you can get rational multiples of the imaginary root i (√-1), they are not "truly" rational numbers because they can't be expressed in terms of real numbers alone
