I do think most "real-world" projects (i.e. modeling physical systems) use floats. (Unless you're talking about book-keeping operations like iteration variables and counters, which I suspect only make a small contribution.) Collatz, on the other hand, exclusively runs using (integer) mod and division operations. I don't see how floats could enter those computations. More generally, I suspect the projects which substantially mix integers + floats are in the minority.

Maybe we could do an approximate conversion from IOPS to FLOPS, but not bother with single vs double precision? I do agree several numbers are bad for presentation, so definitely good to avoid that.
