[GRASSLIST:4721] Re: Fractional Contours from r.contour?

[William K]

I noticed this recently also - the problem lies in that the contour 
levels are put in the cats, which can only be positive integers.  This 
was fixed in a recent 5.7 CVS.  Now it puts the contour levels as a 
float in an attribute table.  Only for 5.7 though, since it needs the 
new vectors of 5.7.  Don't know if the developers can do anything for 
5.3.
