A question posed as an example: converting 1.55 and 0.55 inches to cm.
1.55 * 2.5400000000... = 3.937 which rounds to 3.94 cm per the rules
and
0.55 * 2.5400000000... = 1.397 which rounds to 1.4 cm per the rulesIf both inputs are known to the same precision (hundredth of an inch), why are the outputs not known to the same precision (tenth or hundredth of a cm)?
