	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"		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)		But, in the sort of context where this line algorithm would be useful that I have seen, screen coordinates are always have been non-negative integers, so in practice this kind of ambiguity should not matter. --[[User:Rdm\|Rdm]] 15:52, 4 June 2012 (UTC)
