true except...

Most step motor drives will at least do half stepping, which would be .9 degrees per step, or 400 steps/rev, and a lot of step motor drives will do microstepping, like 10 microsteps per full step, or 2000 steps/rev.

Of course sometimes the microsteps are not exactly the same as each other, so you might not *really* have .0001 accuracy/precision.
