      Description

      A DESCRIPTION OF THE PROBLEM :
      j.l.Math only exposes a floorDiv() family and not a ceilDiv() family as well.

      When determining how many blocks of size n are minimally needed to host m items, for example, the computation behind the scenes is something akin to ceilDiv(m, n). I guess there are many customized ceilDiv()-like computations in the code base, probably some of them incorrect at the extrema of the int/long ranges. Thus, an official ceilDiv() family is certainly helpful.
