	That did it! The time (with the range fix) is now at 461.67 :) I don't
know why I had decided that it wouldn't work with negative numbers when
I first looked at it. Of course the range is still limited to what a
"long" can contain, but that's pretty big...

	Now I've got an interresting puzzle: knowing that "x_ix" and "x_jx" are
both doubles, why is this:
x_jx = 1 - x_ix;
faster than this:
x_jx = 1.0 - x_ix;
??

	I would understand slower (since there is a conversion to do) or same
speed (if the compiler is smart enough to do the conversion at compile
time), faster??
