[~mattjuntunen] for example, in graphics, you might want to place an object
exactly two-thirds of the way between two points. Or in machine learning,
dividing a vector that represents this dataset based on a ratio (such as 80:20
or 70:30). Or in GIS.
One thing i would love to do is to go through the apache projects, see which
ones already depend on the math library, and see if they implement some math
stuff that could be replaced by a call to commons math or move that function to
the math library. Would such cases be considered valid for implementing new
math algorithms inside the math libraries? I don't think i have seen any ticket
that wants to implement new math algorithms

> It takes a vector, say, u = (10) and divides it with ratio, say 1/2. That
> will return a pair of vectors v = (3.33) and w = (6.66). Regardless of
> dimensions, both vectors start at the point of origin
