Yup. Although I'd like to add a typical issue when there's a small change in a large quantity. Say time. If you measure time in microseconds, and use floats, your precision will be halved to 2 us in just 33.5 seconds. In 24 hours, the precision has detoriated to over 2 milliseconds. One famous example is the deadly Patriot missile bug: https://sdqweb.ipd.kit.edu/publications/pdfs/saglam2016a.pdf https://sdqweb.ipd.kit.edu/publications/pdfs/saglam2016a.pdf > Furthermore, you're more likely to use nastier equations (logarithms and exponents are particularly bad for precision), so single-precision could well introduce error with real-world consequences. Some other ones are iteration and simply long computation chains introducing systematic error.
