Pseudo-Random Number Generator otherwise called PRNG is a concept that involves producing a series of random numbers using mathematical formulas. Generating a random number is not as easy as it looks. When we have an algorithm and set of inputs, we get output. And if we again use the same algorithm with the same set of inputs, we get the same output and not a different one. We cannot produce a truly random number using any algorithm. But we can produce pseudo-random numbers for which the numbers are almost unpredictable that it seems like a random number.

There are several algorithms available to produce PRNG. We will be seeing a couple of basic algorithms to understand the concept and implement them using javascript.

Middle Square Method in JavaScript

This is one of the simplest algorithms to produce a Pseudo-random number. It has the following step.

Generating Random Numbers In C or C If you checked most basic random number generation program in C, you might have some knowledge about rand function in C which is used to generate random numbers.

Take a seed value (s), of fixed length/size (n), example, n = 4 and s = 1242
Square the value of s, the resultant value will atmost be of length 2 times of n, if not padd 0 to the left of the resultant value, and let’s call it as S. Example sqr(s) = 1542564, S = 01542564
Take the middle 4 digits from S. It is the random value obtained using the seed value s. Example, random number = 5425
Now use this random number as the new seed value and generate the next random number by following step number 2
If you want the number between 0 to 1, divide the resultant number by the maximum number that can be formed using n digits. For example, 5425/9999 = 0.54255425542

Generate Random Number Javascript

In Project Setup stage for deploy, VS 2012 will be used. Express versions will work except the project setup for deployment. The app is a very simple random number generator with two buttons (Generator/Reset), 7 Labels for the display of the random numbers with a PictureBox.
As C does not have an inbuilt function for generating a number in the range, but it does have rand function which generate a random number from 0 to RANDMAX. With the help of rand a number in range can be generated as num = (rand % (upper – lower + 1)) + lower.
This is me making a Random Number Generator in Dev C, I hope you like it, please give it a thumbs up & subscribe:) Click here to see my other cool program.
To generate random numbers in C programming, use the function rand to generate and print random numbers.

Linear Congruential Generator in JavaScript

Linear congruential generator is a popular PRNG algorithm and it is used in lots of programming languages and systems. It is simple to implement and faster to execute. It is also a way lot better algorithm than Middle Square Method.

Formula : Mac tools em700 manualdwnloadblock.

where,
seed, 0 < seed < m is the initial value that is provided to the algorithm,
a, 0 < a < m – is the multiplier,
c, 0< c < m – is the increment,
m, 0 < m – is the modulus.

To produce a random number between 0 and 1, we divide the generated number by m. The random number generated will be used as seed value to generate next random number.
