Press the green flag, and then choose a Seed value. Now, pressing the Green button will return a series of random numbers. Try different seeds. Using the same seed will get the same numbers... maybe you can use that in a project?
This is an implementation of a PRNG using a Linear Congruential Generator - specifically, the MINSTD algorithm. Such generators are cryptographically weak, but they are fast and do not require tracking more than one state value. So, they are good for embedded applications or low-resource environments. Why not just the "Pick Random" block? Because this gives control over the seed, and could be useful for procedural generation in your projects.
