I'm saying that on the PC's you can afford integer will always be quicker than the FPU for integer calculations. Bob as a professor is not limited by a price of a machine. It's like saying: "there are cars which travel at 30000 miles an hour", seeing the space shuttle as a car. Best regards, Vincent
