(real? (* +i +i)) -> #f

Hi I am playing around with Guile 2.05 on Kubuntu 12.04, why : scheme@(guile-user)> (real? (* +i +i)) $13 = #f but : scheme@(guile-user)> (zero? (imag-part (* +i +i))) $14 = #t thxs -- View this message in context: http://old.nabble.com/%28real--%28*-%2Bi-%2Bi%29%29--%3E--f-tp34250234p34250234
