I don't see why. For example: > (exact? 17.5) #f > (= (/ 35 2) 17.5) #t > (rational? pi) #t Right now, all real? numbers are rational, and all inexact numbers k are `=' to (inexact->exact k). I don't see what that has to do with integers in particular. -- sam th sa...@ccs.neu.edu _________________________________________________ For list-related administrative tasks: http://list.cs.brown.edu/mailman/listinfo/plt-dev
