-1.#IND Returned by Cell Statistics: STD

I calculated the local standard deviation of 1,000 input rasters using the cell statistics tool, and many of the cells returned values of -1.#IND.  I haven't been able to find anywhere what it means, or how to address it.  When I export it as an ASCII grid to use in another program (R), this value imports as a -1, which is problematic.

It looks like these values may be returned for cells where the input values are identical across the local cell values. (I haven't checked everyone of them, though).

Does anyone know what this is?  I've tried searching the ESRI support, as well as Python, and haven't been able to find anything yet.
