Hello bearophile,
Even if you are right, real-life programs often need to process good amounts of memory, so using reals they are slower.
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. -- ... <IXOYE><
