At one time the USA's NASA (*National Aeronautics and Space
Administration*) used Integer math to track their satellites. I don't
know if NASA is still using Integer math or has gone to Floating Point
math for the calculations now.

Agree on the whole that summing is summing is summing. Most DAWs
these days will use floating point (either 32bit or double
precision) and A+B=C no matter what.
