## How to Generate Random Numbers using the Tool?

Generate Random Numbers with Min and Max Range

• To generate within a given range, enter Min and Max number. For example, to generate between -10 and 100, Min will be -10 and Max will be 100
• To get a list of numbers, change the count in the field labelled as 'How Many'. The default is 1
• Click on 'Generate' button
• The tool will generate a list of integers as per the setting. It will generate non-duplicate numbers by default
• To get with duplicate numbers, you can enable the 'Allow Duplicates' option
• Click on 'Refresh' to get a fresh set of numbers
• To pick a number at random, set Count as '1' and enter min and max appropriately. For eg to pick a number between 1 and 3, enter min as 1, max as 3 and click Generate.

How to Generate for a Specific Number of Digits?

• To generate based on number of digits, you have to simply set the min and max appropriately
• For example, to generate 3 digit random numbers, set min as 100 and max as 999. Click on Generate

How to Generate Random Decimal Numbers?

• Click the option 'Include Decimals'.
• Enter the Number of Decimals needed. Default is 1
• Enter the Min and Max Range. Click on Generate

The table below captures a few scenarios with min and max configuration

ScenarioMin (inclusive)Max (inclusive) Example: Your Random Number is
Random Text Number with length 5 10000 99999 36938
Random Text Number with length 8 to 10 10000000 9999999999 2854862020
Pick a number between 1 and 2 1 2 2
Generate random number 1 to 25 1 25 23
Pick a number between 500 and 1000 500 1000 834
1 digit generator 0 9 3
2 digit generator 10 99 42
3 digit generator 100 999 902
4 digit generator 1000 9999 7277
5 digit generator 10000 99999 83856
6 digit generator 100000 999999 954339

## What Algorithm is used by Random Number Generator Tool?

• There are two main types of random number generators: pseudo-random number generators (PRNGs) and true random number generators (TRNGs).
• PRNGs use a program/algorithm to generate a sequence of numbers that are random.
• TRNGs are based on physical elements such as atmospheric noise or hum to generate random numbers.
• This tool generates Pseudo Random Numbers from Rand library.
• You can set Integer ranges from -2147483647 to 2147483647 in this tool

## Frequently Asked Questions on RNG Generator

• RNG stands for Random Number Generator.
PRNG stands for Pseudo Random Number Generator

• Pseudo random number generator.

• True Random number generator.

• True Random number - This is also called Non deterministic random number.
It is based on hardware and other combinations of noise.
Pseudo Random number - This is also called Deterministic random number.
This produces predictable output and more of software program based.

• This tool can pick a number from a range.
Configure the min number and max number to the range with count as 1.
To pick a number between 1 and 5, configure min as 1 and max as 5 and click generate.

• Mersenne Twister (MT), Linear congruential generators (LCG) , Multiplicative Congruential Method (Lehmer Method), Lagged Fibonacci to name a few of them.

• It stands for Deterministic Random Bit Generator.
It is same as Pseudo random number generator.
