OK, well, I thought exactness didn't matter given that R7RS explicitly provides
"(lcm 32.0 -36) ==> 288.0" as an "inexact" example. So "32" and "32.0" are both
fine, but "0.0+32.0i" is not (even though it is computable) because the "exact"
version "0+32i" is not supported? (Odd, in my opinion.)

How would that work, would you be able to elaborate?

Many thanks,
Fredrik
