Ok, I have discovered what is happening.
Your formula is 6.375/{a}
your {a} are various values
Since you had mentioned: correct answer should have '2' decimal figures, the dataset has calculated the answers only upto 2 decimal figures...thus 1.59 is one of the answers.
The bug is: when you fill in the answer in the question, it is not limiting itself to 2 decimals.
so try filling the follwing answers:
1.59---> incorrect
1.593---> incorrect
1.5937---> incorrect
1.59375---> Correct
Surprise!! surprise!!
Want more surprise?
Here you go===> this behaviour does not change even if you change the setting of 2 decimals to 3 significant figures.
Therefore, the bug is=> the decimal/significant figure option is affecting only the dataset for wildcard replacement but fails to be applied when answers filled in are matched with possible answers.
File a bug report Debra.
And sorry for being so presumptuous to call it a numerical question.
