ratnormal rewrites an expression using
its irreducible representation. The expression is viewed
as a multivariate rational fraction with
coefficients in ℚ (or ℚ[i]). The variables are
generalized identifiers which are assumed to be algebraically independent.
Unlike with normal, an algebraic extension
is considered as a generalized identifier. Therefore ratnormal
is faster but might miss some simplifications if
the expression contains radicals or algebraically dependent transcendental
functions.
