Description

  1. allow decimal numbers for approx, e.g. approx=0.07
  2. specify the number of points awarded if the the last digit is +/- 1
    Example: say the result is 1.23 (\AMCnumericChoices); if a student writes 1.22 or 1.24 (e.g. rounding error), he or she will get the number of points specified in e.g. scorelastdigit
  3. specifiy the number of points awarded if one of the digits coded when using \AMCnumericChoices is wrong
    One should be able to specify the number of digits that are wrong (default 1) and the points awarded for that, e.g wrongdigit{1}{1.5} or wrongdigit{1.5} meaning that 1.5 points are awarded if one digit is wrong and wrongdigit{2}{0.5}: 0.5 points if two digits are wrong.
  4. relative error: e.g. relerror=10 and scorerelerror=0.5: if the result (\AMCnumericChoices) is within a range of +/- 10% of the correct result, the candidate receives 0.5 points.
    If formulae are allowed for approx (see also 1. above), then this would be easy to implement: approx = 0.1 * \VQa, if \VQa is the correct result.

5.
The wrong sign (e.g. +1.23 instead of -1.23) yields the number of points specified in e.g. scorewrongsign.

Thanks!

A possibility to check, if all the scores are implemented correcty, would be great.

Example:
say the result is 1.23 (\AMCnumericChoices)
scoreexact=3
scorewrongsign=1 or even scorewrongsign=scoreexact/3 (new feature in global settings: \AMCnumericOpts)

It would be nice, if the solutions could be annotated (similar to annotated papers):
1.23: 3 points
-1.23: 1 point

Thanks!

1. allow decimal numbers for approx, e.g. approx=0.07

It would be great if this feature could be implemented soon. I really miss this possibility!
If the correct result is 1.72, then I would like approx=0.17.

1. Note that the approx value corresponds to the integer number that is coded without the decimal point. If the correct value is 1.72 and decimals=2, approx=17 should do what you need.

2. Perhaps approx=1,scoreapprox=xxx is what you need.

Great! I did not get it, that one has to omit the decimal point ...
Thanks for the hint, Alexis!
So, 1. and 2. are solved.

There is no workaround for 4.? Formulae do not seem to be acceptable for approx, correct?

Formulae do not seem to be acceptable for approx, correct?

That's correct, but you can calculate with LaTeX (using fp package or similar), and then insert the result with something like approx=\computedapprox

Thanks for this hint as well, Alexis!

So number 4 is solved as well. :-)
