== REXX comment ==
The new REXX entry currently says "Apparently, there may be an error in the definition of the algorithm (which only manifests itself with negative numbers): use of the IPART function should probably be FLOOR"
But, in the sort of context where this line algorithm would be useful that I have seen, screen coordinates are always have been positive numbers, so in practice this kind of ambiguity should not matter. --[[User:Rdm|Rdm]] 15:52, 4 June 2012 (UTC)
