Joost Meulenbeld Random number functions

Joost Meulenbeld

Functions for getting random numbers. The rand_gaussian() internally uses the rand_uniform(). rand_uniform() uses rand() internally which is initialized with the current time on rand_init(). This means that the board doesn't need an internal rng but comes at the cost of more computations.

Usage: rand_init(); // initialize once

float random_number = rand_uniform();
