[plt-scheme] programmaticly change display of rationals

In DrScheme, right clicking on a rational gives three options:

* view decimal expansion
* view as mixed fraction
* view as improper fraction

I know the function (read-decimal-as-inexact #f) will let me type rationals such as 1.1. Is there function like that for displaying them as well.

I'd like (* 1.1 0.1) to display as 0.11 instead of 11/100 by default.
