Question about Collision Missile angle speed

Is the angle speed actually angular velocity (i.e. can it be negative)?

And what are the units? degrees/sec, radians/sec...

I think it is degrees/second and it can be negative, dunno how that one works with seeking missiles

Thx.

EDIT: wow I'm retarded and don't know geometry...

So if I wanted a missile to track a circular path, I could ostensibly put in:

v for the missile's move speed

v / ( radius ) * bj_RADTODEG for the missile's angle speed?

EDIT: tested and it works.
