NUMBER SIGN UNSIGNED_NUMBER IMAGINARY_UNIT
And not
NUMBER NUMBER IMAGINARY_UNIT

Because the latter would allow, say, "2 3i". I think there should always be a + or a - between the real and imaginary parts in this kind of notation.

I goofed and missed that case in my list of accepted formats. The code does, in fact, handle this.
The imaginary unit does not have to be preceded by a number; 1+i and 1-i are valid, and so are i and -i.
