Hi,
According to Kopka and Daly (Section 7.4.10 in the 4th edition), one is to use
\mathrm{i} for the special number i to emphasize that it's not a variable. The
same goes for e, pi, and the differential operator d.
These are the recognized standards for typesetting mathematics (apparently).
I don't actually use i, I actually use j instead which is the typical
engineering convention.
Cheers,
Tim.
