Dissecting CastRay... what is the variable 't' in RayInfo for?

I'm dissecting CastRay due to the fact I'm dealing with a problem stated here:

While checking the code of SceneObject's CastRay, I often see the variables currentT which holds a fixed magic number of 2.0f, and the other is the F32 t variable of RayInfo. What exactly do these variables mean? What's the magic number 2.0f for?

I think rayInfo.t represents the distance along the line between the start and end points of your cast ray when the collision occurs. I beleive it is in the range [0..1]

As for currentT, no idea :)
