> Doc bug in floorMod()
> ---------------------
>
> Key: MATH-1237

> Project: Commons Math
> Issue Type: Bug
> Reporter: Ken Williams
> Fix For: 4.0, 3.6

>
> The docs for {{floorDiv()}} and {{floorMod()}} (both the {{int}} & {{long}}
> methods) say things like:
> Finds q such that a = q b + r with 0 <= r < b *if b > 0* and b < r <= 0 *if b
> > 0*.
> That latter clause is probably supposed to be "if b < 0" - this should be
> clarified since (AFAICT) the whole point of these functions is to change the
> behavior from native ops when {{b}} is negative, or maybe when {{a*b}} is
> negative, but I'm not really sure which.
> As an aside, it would be great to add similar methods when {{a}} is a
> float/double, because Java's mod/div operators support float/double types too.
