NPC movement with OgreNewt

I've been trying to get my NPCs to walk for quite sometime now though with no luck. While the logic behind moving bodies should be no different for NPCs -- I'm stuck with having able to stop them just at the right location. Basically, I am doing a setVelocity in the direction of my destination and doing a getPosOrient on every frame to check if the NPC's current location matches the destination. But the NPC's position never exactly matches my destination vector. Am I missing something here?

Thanks!

Don't check for equality, check for <= or >= i.e vicintiy. Comparisions with floats can be weird.
