Comment(by dustymugs):

 +1 for closing.  There was a genuine issue with 1-raster ST_MapAlgebraExpr
 where the returning value from the expression had to be a double
 precision.  Anything else being returned from the expression resulted in
 NULL.

 The output I'm seeing from my examples above look correct and are behaving
 as expected.  I'll try nicklas' attached example and see if the output
 matches what the expression indicates.
