Ive done a quick search on the MSDN libaries and havent come up with anything useful my first impression leads me to think... eg a random number between 0..1 with 2 units of precission.... you could randomly generate a value for 0..1000 then divide it by a 1000 ? would this work ? or is their any easier way ?

Try

float frand() { return float(rand())/RAND_MAX; }

between 0 and 1 with 2 digits after the decimal would be divide by 100, or mulitply by 0.01

float inline frand (){	return (std::rand () % 100)*.01; }
