For all the questions in our question bank, we set all `[[input:ans1]]` with “Input type = Numerical” and “Forbid float = YES”, because the answers must be in integer form only. An exception is made for the problem sets which involves calculating distance between two points using the Euclidian distance formula and resulting in square root of a number. For this case, we set “Forbid float = NO”, and “Allowed words = sqrt”. Students are allowed to input their answer in the form of surd for irrational number without the need to round it, and therefore they don't need to use calculators to do these quizzes.
