Really? It doesn't work for me.

import std.complex;
import std.stdio;

void main()
{
     cdouble z2 = 10 + 1.5e-6i;
     Complex!(double) z;
     z.re = 10;
     z.im = 1.5e-6;
     writefln("z= %.16f z2 = %.16f", z, z2);
}

Prints:
z = 10+1.5e-06i z2 = 10.0000000000000000+0.0000015000000000i

Haven't tested, but docs state that

"Note that complex numbers are floating point numbers, so the only valid  
format characters are 'e', 'f', 'g', 'a', and 's', where 's' gives the  
default behaviour. ***Positional parameters are not valid in this  
context.***"

I'd suggest trying one of those other format types without the numeric  
parts.
