Module name: purrs
Changes by: zolo(a)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.
