Create an AssessmentFunction for a distance quantity question with a tolerance:

Use it to assess answers specified in any compatible unit:

Assess the distance from the Earth to the Sun, allowing a 10% margin of error:

Give an answer in kilometers:

Provide an answer computed based on the time for light to reach Earth:

Generate building height data for use in an answer key:

Create an assessment using the data with multiple scores and a tolerance:

Verify all the values and scores in the answer key:

Assess an answer and retrieve the score directly. The score corresponds to the closest answer key given the tolerance:

Retrieve hydrogen spectra wavelengths and combine values within an angstom:

Create a QuestionObject for reading a spectrum diagram:

The "Quantity" comparison method will be automatically inferred if all the answer keys are Quantity expressions:

Otherwise the fallback "Expression" comparison method will be inferred:

The "Quantity" comparison always automates unit conversion:

To prevent unit conversion and require that answers exactly match the answer key, use a different method like "Number" or "Expression":

When an assessment has zero tolerance, the comparison is performed at machine precision:

Equivalent quantities are considered correct:

Small deviations are considered incorrect unless they are are less than machine precision:
