Hello, With the latest (as of 2012-07-05) version of Rakudo from nom branch I get % ./perl6 -e 'printf "%mf\n",1+2i' 'm' is not valid in sprintf format sequence '%m' in sub sprintf at src/gen/CORE.setting:2067 in sub printf at src/gen/CORE.setting:2072 in block <anon> at -e:1 Although, according to the spec, it's supposed to work. I thought this would be trivial to fix and started looking into doing this myself but unfortunately I got completely lost. AFAICS sprintf() is implemented in src/core/Cool.pm but it simply forwards to Parrot. And I have no idea what is the right thing to do here: modify Parrot to support "%m" (but does it even have complex numbers?)? Massage the format string and the arguments to transform "%m" into "%f+i%f" or something like this and the complex number into its real and imaginary parts? This should work but looks clumsy... So I'm afraid it's not as trivial as I thought or at least not sufficiently trivial for me to fix it myself. Hopefully somebody else can do it. Thanks, VZ
