minus-squareMoobythegoldensock@lemm.eelinkfedilinkarrow-up2arrow-down1·9 个月前It is fixed. Your ruler shows 1.0, and then you estimate 1 digit past to 1.00 +/- 0.01.
minus-squareSpaceNoodle@lemmy.worldlinkfedilinkarrow-up3·9 个月前You’re not making any estimation within 1/10 like that. 1/2 is as close as you can reasonably get.
