FWIW, I see Luke's behavior using 5.0.2 on login.ccs.neu.edu.

The numbers I get in DrRacket/ISL+:

#i-0.49746596003269405
#i-0.49746596003269405
#i-4974659600326941.0
#i-4974659600326941.0

Linux login 2.6.31-22-generic #60-Ubuntu SMP Thu May 27 00:22:23 UTC 
2010 i686 GNU/Linux

On the other hand, I get different numbers using 5.0.2 on my own machine.

#i-0.4974659600326926
#i-0.49746596003269405
#i-4974659600326926.0
#i-4974659600326941.0
