Exactly, that is the one case where float and double are better, where large 
volumes of data need to be processed, normally in a regular fashion. For 
cases where small amounts of data are processed and where there is littler 
opportunity to use vectorization, they have little or no advantage over real.

And I suspect that both kinds of code occur with some regularity.
