CVSROOT: /cvs/ppl Module name: ppl Changes by: zaffanella@cs.unipr.it 2006-09-24 17:58:30

Modified files: src : Octagonal_Shape.templates.hh

Log message: Use is_additive_inverse() to improve readability in several places. Used is_even() in tight_coherence_would_make_empty(). Corrected bug in the output operator whereby the output of an octagon having integer coefficients could have been innacurate (but correct).
