Bill Bell commented on SOLR-4911:
---------------------------------

There might be a bug.

+    if(valsArr.length == 0)return 0.0f;
+    float val = Float.POSITIVE_INFINITY;

should it return Float.POSITIVE_INFINITY; ?

+    if (valsArr.length == 0) return 0.0f;
+    float val = Float.NEGATIVE_INFINITY;

And this return Float.NEGATIVE_INFINITY; ?

I know the original code always returned 0.0f but wou;dn't this set the floor 
or ceiling as 0.0f?
