 Replying to [comment:1 glynn]:

 large maps, and is significantly more efficient.

 IMHO, it would still be nice if `r.univar` supports floating point
 percentiles. The `r.univar` manual could mention that `r.quantile` is the
 better choice if only quantiles and/or percentiles are requested, e.g.
 under NOTES where it already says that `r.univar` can use large amounts of
 system memory for extended statistics. I would suggest to also add
 `r.quantile` to the SEE ALSO section.
