CVSROOT: /cvs/purrs Module name: purrs Changes by: zolo@cs.unipr.it 2003-06-27 16:10:43

Modified files: src : Expr.defs.hh Expr.inlines.hh Expr.cc

Log message: Implemented the new methods `Expr::is_rational_scalar_representation()' and `Expr::is_rational_polynomial()' and removed the old `Expr::is_rational_polynomial()' that only tested the GiNaC's flag `GiNaC::info_flags::rational_polynomial'. Moved the function `sqrfree()' from the file Expr.inlines.hh to Expr.cc: now, before to call `GiNaC::sqrfree' on a expression, every occurence of polynomial expressions for PURRS but not for GiNaC (e.g. log(2)) is substituted with an arbitrary symbol and, after the decomposition with `sqrfree', come back to the original expression.
