Stepper does not respect "Fraction Style"

[LiberalArtist]

The teaching languages allow you to set the "Fraction Style" to either "Mixed fractions" or "Repeating decimals":

However, the Stepper does not respect this choice. For example, 8.30167 (in HtDP lexical syntax, so an exact number) is printed by the stepper as 830167/100000, which is neither a "mixed fraction" not a "repeating decimal".

I haven't investigated the other options under "Output Syntax".
