In the answer drop-down menu, select one of three answer formats:

**Exact answer** [1]: Enter the exact answer with the exact error margin allowed. For example, if the answer were 2.12 with a 0.01 margin of error, the quiz accepts any response between 2.11 and 2.13 (inclusively). By default, the margin is 0.

**Answer in the Range** [2]: Enter the range of answers that can be accepted as correct, such as answers between 8 and 10.

**Answer with Precision** [3]: Enter the answer with the precision number. The precision number is how many digits are expected in the answer. Precision answers can be negative numbers and may include trailing zeroes. However, student responses will be marked as correct if they omit the trailing zeroes, as long as all preceding digits are correct.

By default, the precision number is 10, but answers can be rounded to a precision of up to 16 in standard or exponential format (e.g. 1e+26). Answers are accepted with or without the **e** exponent and are formatted according to the configured precision. Any numerical entries past 16 are truncated for grading and comparison. If any of the potential answers to a numerical question are a precision answer, then the student answer fields will accept precision answers.

If none of the possible answers are precision answers, the student answer fields round to four decimal places.
