Numerical questions provide a field for a single numerical value. The label beside it can specify units, decimal places, and an acceptable margin of error.

​
Enter Your Answer

Read the label, calculate your answer in the requested units, and enter the number. Leave units out of the field itself. For example, if the label asks for speed in m/s, enter 15.0, not 15.0 m/s.
A question about travelling 150 metres in 10 seconds, with 15.0 entered in the numerical response field.A question about travelling 150 metres in 10 seconds, with 15.0 entered in the numerical response field.

The label specifies metres per second and one decimal place.

How Rounding Affects Grading

For questions with decimal place requirements, Uflo checks your answer in three steps:
1

Round Both Values

Round your response and the expected answer to the specified number of decimal places.
2

Compare the Rounded Values

Calculate the difference between them.
3

Check the Result

Without a margin of error, the rounded values must match. With a margin, the difference must be no greater than that margin.

​
Example

Question: A cyclist travels 22 metres in 7 seconds. Calculate their average speed in metres per second, giving your answer to two decimal places. The expected answer is 22 ÷ 7 = 3.142857… m/s, which rounds to 3.14 m/s. Two number lines show the expected answer rounding to 3.14. With exact matching, 3.144 is accepted and 3.154 is not. With a margin of 0.02, rounded values from 3.12 to 3.16 are accepted, so 3.164 is accepted and 3.174 is not. Two number lines show the expected answer rounding to 3.14. With exact matching, 3.144 is accepted and 3.154 is not. With a margin of 0.02, rounded values from 3.12 to 3.16 are accepted, so 3.164 is accepted and 3.174 is not.

Both values are rounded before grading. A margin of error widens the accepted range.

With no margin of error, your response must round to 3.14.
