The internal value in CAS is exactly: If by "inexact" you mean "floatingpoint reals", then you are not correct. In CAS, reals use 48 bits for the mantissa, and are therefore exactly equal to an exact integer divided by an exact power of 2, which is therefore representable as an exact terminating decimal number. For example, the value of approx(1519/99) is stored by CAS as 134962275764989/2^43, which can be written exactly as the terminating decimal number I gave above. <0ΙΈ0> Joe
