Add a random() function about epsilon

[mateoconlechuga]

Do we want functions such as randInt(), randNorm(), randBin(), along with a way to seed random numbers using a rand style variable? It would help match other calculator variants.

a way to seed random numbers using a rand style variable

This could actually be a great opportunity to teach students the difference between pseudo-randomness and actual randomness. These two concepts have long been improperly mixed up :-) We could do both and give them appropriate names (e.g. random() and pseudoRandom() would seem like a great start).

Hi,
Now that the Python app has the glorious >>> wouldn't it be easier and perhaps more useful to have the random module (or a smaller version). Or did you want to have random() in the calculation app?

Hi,
I also want this for my students, when introducing simple statistics.
So I have compiled epsilon with support of Python library urandom (the random library of Micro Python). Works like a charm. I have the following random functions :

• seed(int)
• random() : float between 0 and 1
• randInt(int start,int stop) : integer between start and stop
• randrange(int stop, int start, int step) : integer between start and stop, search with step (start and stop not mandatory)
• choice([a,b,c,...]) : choose item randomly in array [a,b,c,...]

Do I make a pull request for this ?

@maxBzh Release early, release often! I'm interested, and I may not be the only one.

@Grahack Here you go #295

Thank you @maxBzh ! Definitely something we wanted to do so your PR is very much appreciated! Thank you very much!
