How sure are you that the floating point number underneath has really not set the negative bit? Maybe try to .clip() the grid positions before on the numpy level to (0.0, \infty) where 0 arises from a fresh parse of '0.0' by the interpreter, i.e., a "really really zero" fp number. To clip, you may also use grid *= (grid > 0) or similar things of that fashion. I'm not sure if the mistake is implied my your side of the code, but i just hope this helps maybe. The Locator stuff is not soo easy.
