We do if only 1 calculation is involved. I need to test motion profile generators. Most of the time the resolution is close to 12 to 13 digits. However, I must test for worst case.
I have run a test that tries 200 trillion motion profiles. The worst case had errors where the precision was only 10 or 11 digits.
1xE-13 is pretty small but if you really need it then I agree, REALs won't do.
Even with DREALs you would lose lots of digits adding 1 and 1xE-13
you used to blow my mind by rolling your own pid's back in 2002.
