Thanks, Josh. I was having trouble a couple of minutes ago remembering  
this. Getting old, I guess. In constructing my thanks to Josh I tested:

print(mat, digits=2)

  ... and also got what I had been aiming for with my results. The  
print strategy has the advantage that the underlying data is not  
mucked with.
