%%%When using the Screw Tool in Edit Mode, the expected behavior of the tool is to divide 360 degrees/steps per turn.
Blender isn't dividing 360 degrees/steps per turn, Blender is dividing less than 300 degrees/steps per turn.

Steps to reproduce this error:

Using factory Blender settings, change from Perspective to Orthographic, use NumPad 1 to view from front Ortho, enter Edit Mode and delete all of the cube vertices, then, using the CTRL Click, add two vertices and an edge. Using the transformation Panel, adjust them to coordinates X,Y, Z for the first vertex to (-1,0,-1) and the second to (-1,0,1). Press A to select them all,. and place the cursor in (0,0,0) coordinates. Press Screw and look at the angles. If you divide 360 degrees for the number of steps, for some dividers (3, 6, 8, for example) this should return an integer division (120, 60 and 45 degrees, respectively), but this is not happening. What's happening is a division by near 300 degrees.

I have also sent 2 attached files showing the problem. In one, press screw, in the second, you can see the angle values.

Using 2.49b, the Screw Tool in the F9 Panel is working well.

This Bug was filled because I'm writing the Screw part of the Blender Wiki - User Manual.
