I have been writing software for decades in areas ranging from industrial control to large business systems. I almost never use floats or doubles. In almost all cases 32 bit integers (and sometimes U64int) with some scaling suffices.

Perhaps it is the FORTRAN overhang of engineering education that predisposes folks to using floats when Int32/64 would be fine.

I shudder as to why in JavaScript they made Number a float/double instead of an integer. I constantly struggle to coerce JS to work with integers.
