Intrinsic functions aren't functions at all, as I understand it. They translate
directly to assembly instructions. If there's no assembly instruction to do some
math operation, then you won't find an intrinsic for it. :)

Of course, instrinsic functions are converted to asm directly. I ment that the
functions from math should if possible on this platform be instrinsic and if not
be normal functions. So you would be portable, but could still take adventage of
instrinsic functions if possible.

 Look at boost::format. It's typesafe, can be used with userdefined types, but 
 uses a printf-like formatstring. OK, you can't do this in D, because of the 
 limited templates, but if templates might be reviewed it might be an
interesting 
 option. 

I've done this in D without templates. It works pretty nicely.

Could you show me your code?

I hadn't thought of that.  Good point.
