Obosolete: there's now a built-in function
sort_by.Defines a custom function sort_by to sort a list of lists by the elements at the given index.
You could do a similar thing to sort lists of dictionaries.
-
Because JavaScript numbers lose precision as they get bigger, you get some unexpected results.
See the variable "two" - the difference should be 2, but because the JavaScript representation of each of the two numbers is the same, it thinks the difference is 0.
Using the decimal data type, there's no loss of precision, so the correct value is produced.
-
Pick from the range -5..5, but make 0 more likely.
-
Demonstrates how to set up a "choose one from a list" part where the number of choices is randomised.
The part is given a list of labels for the choices as well as a list specifying the marks to award for each choice.
-
This question shows that you can set the number of marks available for a part to a fraction. The total available for the question is 1 mark.
-
A short demonstration of when the basic simplification rules are turned on, or off.
-
Shows how the \text command is rendered using the plain-text font, not the LaTeX one. Useful for displaying units of measurement and English words inside equations.
-
The statement of this question demonstrates how you can control the \simplify command's behaviour by specifying the rules to use.
-
Should not be used: there's now a built-in function
frequencies.This question randomly generates a list of 100 items, each chosen from a list of strings.
It then computes the number of occurrences of each distinct item in the list. The statement shows the frequencies in a table.
-
This question uses the vis.js library to plot 3D functions and data sets.
As well as JME functions to make plots, you can use javascript functions to get more control over how the plots are rendered.

This exam uses a custom theme to provide no feedback about scores to the student.
The idea is to provide a version of the test compiled with this theme to the students as they attempt it. Once the test has closed, update with a version of the same test compiled with the default theme, so students can go back in and get feedback.
-
