Ratdenom

Function: ratdenom (<expr>) Returns the denominator of <expr>, after coercing <expr> to a canonical rational expression (CRE). The return value is a CRE.

<expr> is coerced to a CRE by rat if it is not already a CRE. This conversion may change the form of <expr> by putting all terms over a common denominator.

denom is similar, but returns an ordinary expression instead of a CRE. Also, denom does not attempt to place all terms over a common denominator, and thus some expressions which are considered ratios by ratdenom are not considered ratios by denom.

There are also some inexact matches for ratdenom. Try ?? ratdenom to see them.
