(OP)
Is there a way to format complex numbers in Excel?  I just ran a Fast Fourier Transform (FFT) and the result is a column of complex numbers.  Excel shows the real and imaginary parts out to about 13 places so I need a wide column to see it.  

RE: complex numbers

Hi zappedagain:

Just thinking aloud here ... would using

=COMPLEX(real_num,i_num,suffix)

help?

RE: complex numbers

something like this worked:
=COMPLEX(ROUND(PI(),4),ROUND(PI(),4))

which means that you'll need something like

=complex(round(imreal(YOURVALUE),4),round(imaginary(YOURVALUE),4))

so, decompose to real and imaginary, apply the round function and recompose into imaginary.

RE: complex numbers

It looks like another one of those gaping holes in exel.

Along the lines of what was suggested above.... perhaps you store your complex numbers in column B with a very narrow width (don't even look at C for values), then use imreal() to display real part in column C and imaginary() to display imaginary part in column D... then use normal formatting on columns C and D
