It doesn’t
- Answer, it doesn’t. And it can’t. That is why it’s called a “pseudo” random number generator (PRNG). It means it’s a fake. It’s a knock-off.

Nov 1, 2011 · Math.random() returns a number between zero and one. If I want to return an integer between zero and hundred, I would do: (int) Math.floor(Math.random() * 101)
Mar 15, 2018 · The JavaScript Math.random() function is designed to return a single IEEE floating point value n such that 0 ≤ n < 1. It is (or at least should be) widely known that the output is not cryptographically secure. Most modern implementations use the XorShift128+ algorithm which can be easily broken.
Generating truly random numbers in software is indeed not possible as others have pointed out, however it is possible with hardware to build a device which can generate truly random numbers*. There are quite a few examples of this on the internet, and there are a variety of methods used, from reading the time between ticks on Geiger counter to ...
Mar 12, 2018 · Surprise surprise, the answer is that Math.random() doesn’t really generate a random number. Not exactly. It just does a really good job of simulating randomness. Algorithmic random number generation can’t exactly be random, per se; which is why they’re more aptly called pseudo-random number generators (PRNGs).

_Picture of analog-input digital-output processing device. Photo by Harrison Broadbent_ Let's consider two principal methods used to generate random numbers. The first method is based on a physical process, and harvests the source of randomness from some physical phenomenon that is expected to be random. Such a phenomenon takes place outside of the computer. It is measured and adjusted for possible biases due to the measurement process. Examples include radioactive decay, the photoelectric ef...
_Picture of computer code flowing through computer screen. Photo by Markus Spiske._ As an alternative to "true" random numbers, the second methodof generating random numbers involves computational algorithms that can produce apparently random results. Why apparently random? Because the end results obtained are in fact completely determined by an in...
A computer executes code that is based on a set of rules to be followed. For PRNGs in general, those rules revolve around the following: 1. Acceptsome initial input number, that is a seed or key. 2. Applythat seed in a sequence of mathematical operations to generate the result. That result is the random number. 3. Usethat resulting random number as...
When I decided to write this article about embedding a random number generator within a web page, I had a choice to make. I could've used JavaScript's Math.random() function as the base and generate output in pseudorandom numbers like I have in earlier articles (see Multiplication Chart - Code Your Own Times Table). But this article itself is about...
Apr 11, 2015 · Mathematically random numbers are defined as. Random numbers are numbers that occur in a sequence such that two conditions are met: (1) the values are uniformly distributed over a defined interval or set, and (2) it is impossible to predict future values based on past or present ones.
Nov 3, 2022 · The math.random () method creates pseudorandom numbers through the application of an algorithm. The linear feedback shift register (LFSR) approach is the foundation of this algorithm. In...
