Well, the paper explicitly takes the principal branch to solve this. So it isn't exploiting the branching for computation.

- gus_massa 5mo agoI agree, as the sibling comment there are two different things that are named "branches". Anyway, to get the principal branch in the microprocessor it's necessary to implement "atan2" that has a lot of special cases. For example, IIRC ln( -inf.0 + y * i ) = ´+inf.0 + pi * sign(y)
