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.
