1. Mathematica 7.0 performs differently. 4.0*I looks like 4.I Mathematica 9. does this.. 4.0*I looks like 0.+4.I 2. If you want to do something different, consider something like this: f[x_Complex]: If [VerySmall[Re[x]], Im[x]*i, Re[x]+Im[x]*i] where VerySmall is defined as you wish. Could be VerySmall(x_]:=x==0.0 for example. Note that the answers are no longer complex numbers because they involve the symbol i not I. You can do %/. i->I but then you will see 0.+4.I again. RJF
