"Only" using 15 digits is still pretty insane
You get that level of precision in a standard "
double
" floating point number. So that's basically the normal level of precision you get without trying.M_PI
inmath.h
is like 20 digits. I'm surprised they just don't do that.Google suggests that excel uses 15. So even college students working on any old STEM degree are probably using 15 digits.
