Summary: Doc bug in floorMod()
Key: MATH1237
URL: https://issues.apache.org/jira/browse/MATH1237
Project: Commons Math
Issue Type: Bug
Reporter: Ken Williams
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.
