However the decimal number \(q\) to transform must be \(0 < q < 1\).

Perhaps Continued Fraction route is faster (and less restriction) ?

But this also means that you define the largest possible numerator. #-)

Is it better do let Farey sequence handle fraction of input ?
Numerator can be easily fixed later.

Probably not even need fixing, mixed fraction is a "feature" :-)
