Description of the generator
Our free online generator is designed to generate random integers. It can easily be used, for example, to determine the winning number of your lottery, draw or contest.
Number of simultaneously generated numbers: from 1 to 999. By default, one number is generated.
The available range of numbers is from 1 to 99,999,999 inclusive. In this case, the final value of the range must be greater than the initial value. By default, the range from 1 to 100 is used to generate a random number.
Generated numbers can be sorted: randomly (by default), in descending order, and also in ascending order.
When displaying numbers in the result block, you can use separators: a space (by default), a comma, as well as a combination of "comma + space".
When generating several numbers, the same ones may appear. By default, duplicates are removed. If you allow the same numbers as a result, then just remove the bird in the field "Number Repetitions".
The generator also allows you to copy the result to the clipboard. To do this, use the "Copy" button, the result will be automatically placed on the clipboard.
If you need to return the values of all fields to their original state, you should click the "Reset" button.
A few words about accidents
As surprising as it may be ordinary person, but random numbers play a very important role in various areas of human activity, where sequences of random numbers are required, which no one can predict. The best known examples for us are lotteries or online casinos. After all, if such sequences turn out to be not completely random and someone can trace the order in them, he can easily apply this knowledge to his own interests. So in 1873, the British engineer Joseph Jagger, along with six of his assistants, went to the casino and began to write down the numbers on the roulette tables. Imagine, but he found that on one of the roulettes, some numbers fall out much more often than others, i.e. are not so random! It was then that he began to put money on these numbers. And although the casino owners suspected something was wrong and tried to somehow remedy the situation by rearranging the tables from place to place, this did not help them. Jagger won a total of about $5 million in today's money from them.
Random numbers are also needed in cryptography, for example, to encrypt network traffic or carry out banking transactions. If the generated sequences of random numbers have easily detectable patterns, attackers will be able to intercept outgoing traffic and harm the user's computer or steal his confidential data.
In addition, random numbers are used in various scientific and engineering fields for computer simulation of real natural processes, in statistics, which itself is based on chance, in various gambling(not only because roulette requires chance), etc.
As you can see, chances are in demand. But is it easy to get really high-quality random sequences of numbers or characters? Let's say right away that it is theoretically possible to create such a generator, but it is very difficult to do it in practice. That is why the numbers obtained using various mathematical algorithms are called pseudo-random. There are many varieties of pseudo-random number generators that use the most sophisticated algorithms, but they are still not perfectly random. However, the greater the number of different initial conditions that make it difficult to predict each successive sequence number is used in the generator, the more reliable it is.
So where do truly random events take place? At the moment, science believes that the events of quantum mechanics should be considered random. According to the Heisenberg uncertainty principle, we cannot measure all the necessary parameters of a quantum object with arbitrarily high accuracy. Moreover, in principle we cannot, and not because we do not have enough technical capabilities. And since it is impossible to measure all the initial parameters, it means that it is impossible to predict the exact outcome of the process.
Thus, it is quantum generators that should be considered the highest quality random number generators, i.e. those that use quantum processes in their work.

The presented online random number generator works on the basis of a software pseudo-random number generator built into JavaScript with a uniform distribution. Integers are generated. By default, 10 random numbers are displayed in the range 100...999, the numbers are separated by spaces.
Basic settings of the random number generator:
- Amount of numbers
- Number range
- separator type
- On / off the function of removing repetitions (doubles of numbers)
The total number is formally limited to 1000, the maximum number is 1 billion. Separator options: space, comma, semicolon.
Now you know exactly where and how to get a free sequence of random numbers in a given range on the Internet.
Random Number Generator Use Cases
Random number generator (RNG on JS with uniform distribution) will be useful for SMM-specialists and owners of groups and communities in social networks Instagram, Facebook, Vkontakte, Odnoklassniki to determine the winners of lotteries, contests and prize draws.
The random number generator allows you to draw prizes among an arbitrary number of participants with a given number of winners. Contests can be held without reposts and comments - you yourself set the number of participants and the interval for generating random numbers. You can get a set of random numbers online and for free on this site, and you do not need to install any application on your smartphone or program on your computer.
Also, an online random number generator can be used to simulate the tossing of a coin or dice. But by the way, we have separate specialized services for these cases.
We have a sequence of numbers, consisting of almost independent elements that obey a given distribution. Usually evenly distributed.
How to generate random numbers in excel different ways and ways. Let's take a look at the best of them.
Random Number Function in Excel
- The RAND function returns a random uniformly distributed real number. It will be less than 1, greater than or equal to 0.
- The RANDBETWEEN function returns a random integer.
Let's look at their use with examples.
Selecting random numbers with RAND
This function does not require any arguments (RAND()).
To generate a random real number between 1 and 5, for example, use the following formula: =RAND()*(5-1)+1.
The returned random number is evenly distributed over the interval .
Each time the worksheet is calculated, or the value in any cell in the worksheet changes, a new random number is returned. If you want to save the generated population, you can replace the formula with its value.
- We click on a cell with a random number.
- Highlight the formula in the formula bar.
- Press F9. AND ENTER.
Let's check the uniformity of the distribution of random numbers from the first sample using the distribution histogram.
The range of vertical values is frequency. Horizontal - "pockets".
RANDBETWEEN function
The syntax of the RANDBETWEEN function is (lower bound; upper bound). The first argument must be less than the second. Otherwise, the function will throw an error. The bounds are assumed to be integers. The formula discards the fractional part.
An example of using the function:
Random numbers with 0.1 and 0.01 precision:
How to make a random number generator in Excel
Let's make a random number generator with the generation of a value from a certain range. We use a formula like: =INDEX(A1:A10;INTEGER(RAND()*10)+1).
Let's make a random number generator in the range from 0 to 100 with a step of 10.
From the list of text values, you need to select 2 random ones. Using the RAND function, we compare text values in the range A1:A7 with random numbers.
Let's use the INDEX function to select two random text values from the original list.
To select one random value from the list, apply the following formula: =INDEX(A1:A7,RANDBETWEEN(1,COUNT(A1:A7))).
Normal Distribution Random Number Generator
The functions RAND and RANDBETWEEN produce random numbers with a single distribution. Any value with the same probability can fall into the lower limit of the requested range and into the upper one. It turns out a huge spread from the target value.
Normal distribution means that most of the generated numbers are close to the target. Let's correct the RANDBETWEEN formula and create a data array with a normal distribution.
The cost of goods X is 100 rubles. The entire batch produced is subject to a normal distribution. The random variable also follows a normal probability distribution.
Under such conditions, the average value of the range is 100 rubles. Let's generate an array and build a graph with a normal distribution with a standard deviation of 1.5 rubles.
We use the function: =NORMINV(RAND();100;1.5).
Excel calculated which values are in the range of probabilities. Since the probability of producing a product with a cost of 100 rubles is maximum, the formula shows values close to 100 more often than the rest.
Let's move on to plotting. First you need to create a table with categories. To do this, we divide the array into periods:
Based on the data obtained, we can form a diagram with a normal distribution. The value axis is the number of variables in the interval, the category axis is the periods.
