Announcement text: 
----------------------------------------------------------------------
The rangen package is a package that generates random
integers, rational numbers, and decimal number. Actually,
the package uses the lcg package (by Erich Janka) to
generate random integers, while rangen builds rational
numbers and decimal numbers from the generated integers. My
purpose in writing this package was to be able to create
random questions for the quizzes of exerquiz (part of AeB).
Indeed, that is what you can do with this package: Write a
quiz question based on a template (for example,
differentiate $\a x^{\n}$ , where \a and \n are RVs (random
variables) generated with rangen), determine if the user
input is correct, and display the correct answer to the
question.
