noreprand

A simple random number generator that doesn't have repeating digits

Installation

Type in gem install noreprand inside your command line or terminal.

Usage

Firstly, type in require 'noreprand' at the top of your script. NOTE make sure that the gem is installed Secondly, type in <name of your choice> = NoRepRand.new below the first line. DONE!

Fields

To specify how many digits the number should be, type in a number in the brackets after calling the method raand. (E.g nrr.raand(3)) To specify if the first digit of the number can be 0, type in true or false (without quotation marks) in the brackets after specifying the number of digits. By default this is false. (E.g nrr.raand(5, true))

NOTE For the examples, I have been using nrr.raand this is because in step 2 of "Usage" I had typed in "nrr" inside the field. You can use whatever you want. Just remeber to use that name when calling the method raand.

Example

require 'noreprand'
nrr = NoRepRand.new
puts nrr.raand(5, true)
=> 82659
