Global variable
facsum_combine
Default value: true
facsum_combine
controls the form of the final result returned by
facsum
when its argument is a quotient of polynomials. If
facsum_combine
is false
then the form will be returned as a fully
expanded sum as described above, but if true
, then the expression
returned is a ratio of polynomials, with each polynomial in the form
described above.
The true
setting of this switch is useful when one
wants to facsum
both the numerator and denominator of a rational
expression, but does not want the denominator to be multiplied
through the terms of the numerator.
