[GRASSLIST:4603] direction of drainage map in angle

[orkun]

Hello
I want to get direction of drainage map.
To do this I used r.watershed command. then I got a map which has (-8 -6 
-4 -2 2 4 6 8) values.
In order to have direction of drainage map in angle I multiplied it with 
45 as the manual gives instructions.
But the result map only covers 90, 180, 270, 360 values.
Actually I need continuous values from 0 to 360.

Does anyone have an idea ?

thanks in advance
