Extending from 24-bit to 32-bit adds a lot of precision, but absolutely no accuracy is gained. In the olden days when I was in high school, like all nerdy pain in the arse 13-year-old a few of my friends and I made a big thing of learning Pi to as many decimal places as we could. I can still remember it to about 12 places. Now I've been working in various forms of engineering for 40 years (with some overlap with being a nerdy teenager), I find that for most of that time if I've needed to use Pi to for example calculate the length of cable on a drum I just say "three and a bit, I can coil it up shorter but I can't coil it up longer".
