I'm refreshing my knowledge of calculus and ran into this problem while working on limits.(adsbygoogle = window.adsbygoogle || []).push({});

"Find∗ the value of each of the indicatedlimits to at least 3 digits of accuracyby evaluating f(x) at various values, or state that the limit does not exist (DNE)."

My problem is with "at least 3 digits of accuracy." If I type in an answer like 6.78, it says I'm wrong. If I type in the answer 6.778, it says I'm right. 6.78 has 3 significant digits though, so shouldn't that work?

It doesn't say 3 digits after the decimal point, it says "3 digits of accuracy." Isn't that referring to having 3 significant digits?
