The problem is that today, a lot of programmers remember that and ignore the fact that you can often do floating point math on a modern real time system and meet all your deadlines. Just last week I fixed a bug in such a system: in an effort to speed things up by avoiding floating point math, calculations were done with uint32_t's and the developer(s) didn't notice that in some cases there was an internal overflow before the final result was produced.
