32 is plenty to represent the numbers we care about, but you'll find you probably want 64 to do math with those numbers. 64 has always been enough for me to never have to care about the precision, but whenever I've used 32 to save some ram, I've ended up having to think carefully about how some operation would reduce the precision in a material way.
