Hi -
I'm computing the angle between pairs of unit vectors as the arc
cosine of the dot product of each pair of vectors. Occasionally, when
the dot product is 1.000000 (output to 6 decimal places) I get the
value -1.#IND00 ! What does this mean?
Thanks,
- Olumide
PS: if it helps, I'm using Visual Studio .NET 2003 on a Windows XP
machine.
