An example of what I mean: 174 with a precision of 3 tells us that the tenths place could be any of 0-9, or, put another way, the actual number could be anywhere between 174.0 to 174.9 (or maybe 173.5 to 174.5). If we have 174 with four digits of precision, then the representation should be 174.0 and it's the hundreths we are unsure of. So my question is: if we write 174 when could the thousands /ever/ be anything besides 0? -- ~Ethan~
