Talk:Imaginary base numbers

couple of minor points

When translating the Sidef code to Phix, one thing I noticed is that parse_base() never has to deal with a leading '-', so I took that out. As far as I understand it, imaginary base numbers never use a minus sign. The same unnecessary handling exists in the Perl6 code. Also, the even entries in the second half of the output from Kotlin, Java, Go, D, and C# all fail to trim the unnecessary trailing ".0" (as the heading says, both pretty minor points).
