Using Helmut Richter's example, if instead you wanted the
solutions to x^2 + x - 1 = 0, would you rather see something
like (-1/2) +/- (1/2)(sqrt 5) as the output or see something
like 0.61803398874989, -1.61803398874989? [High school students
reading this might want to see if you can figure out why
the expansions to the right of the decimal place agree.]

The second one, as I'm looking for collision points in 3D space. If I
get complex roots, then I know that there is no collision at all.
