NumericUnits¶

Provides two input fields with Number and Units placeholder texts. This area will also display its associated grading function (as seen in the screenshot below).

Note: this area will display how the user's response was interpred using the interp_string field provided in the feedback object returned by that function (if it exists).

Component Parameters¶

`pre_response_text` & `post_response_text` (optional)¶

Text block to be displayed to the left and right of the input field respectively. Markdown and LaTeX are allowed following the usual syntax.

Comparing units¶

This is done using the compareExpressions evaluation function.

By ticking the physical_quantity (boolean) option in the Evaluate tab, answers with different units from the reference answer can be compared.

physical quantity ticked

For example, if the reference answer is 100 m, the following answers will also be accepted:

0.1 km
10000 cm
10^5 mm

See here for more information

Tolerances¶

This is done using the compareExpressions evaluation function.

Tolerances can be added to your answer using the atol (number) and rtol (number) fields, which denote absolute and relative tolerances respectively.

Response Structure¶

This is how the react component will structure the user's input to the Grading Gateway, when they press the check button.

In this case, the response is a single string which features the user's response to both fields separated by a space.

Example

"response": "150 g"
