Also, it's not very mpl-ish. Nothing seems to follow the metafunction protocol of operating on and returning types.
I hate to be discouraging; it's probably a really interesting idea. I am only looking as far as some details of the implementation, here.
What happened to fixed_c?
Nothing; the stub is still there, waiting for somebody to implement it in full.
It's used here http://www.boost.org/libs/mpl/doc/paper/html/codegeneration.html in a form mpl::fixed_c<9,0001> (he-he). ^^^^
This one is actually kind of nasty -- ignoring the fact that 0001 is an octal constant, there is no way you can detect the number of leading zeros here, which renders this particular representation unusable. I guess we can go with something like float_<0,90001,e<+1> > or something along these lines.
Any plans to redesign it and to put into MPL?
Well, somebody who needs it needs to tackle it. It would be a welcome contribution. -- Aleksey Gurtovoy MetaCommunications Engineering
