minus-squarechiliedogg@lemmy.worldlinkfedilinkEnglisharrow-up1·1 month agoOkay. How do you describe a measurement of 1 and a quarter of a centimeter precise to 1/4cm without either over-stating or under-stating precision of the measurement? Decimal only allows you to increase or decrease precision by a factor of 10.
minus-squareCassanderer@thelemmy.clublinkfedilinkEnglisharrow-up1·1 month agoIf the Precision is necessary you just break up two decimal points, or however many to get it to where it has to be.
minus-squareNobodyElse@sh.itjust.workslinkfedilinkEnglisharrow-up1·1 month agoYou don’t need to use significant figures to convey precision. You can also explicitly state the uncertainty, like 1.25 ± 0.25 cm.
minus-squarechiliedogg@lemmy.worldlinkfedilinkEnglisharrow-up1·edit-21 month agoBut even you don’t know how that works. Because 1/4cm precision would be ± 0.125cm
